Postgres95 1.01 Fri Feb 23 18:20:36 PST 1996
|
|
=========================================================
|
|
Incompatibilities:
|
|
* 1.01 is backwards compatible with 1.0 database provided the user
|
|
follow the steps outlined in the MIGRATION_from_1.0_to_1.01 file.
|
|
If those steps are not taken, 1.01 is not compatible with 1.0 database.
|
|
|
|
Enhancements:
|
|
* added PQdisplayTuples() to libpq and changed monitor and psql to use it
|
|
* added NeXT port (requires SysVIPC implementation)
|
|
* added CAST .. AS ... syntax
|
|
* added ASC and DESC keywords
|
|
* added 'internal' as a possible language for CREATE FUNCTION
|
|
internal functions are C functions which have been statically linked
|
|
into the postgres backend.
|
|
* a new type "name" has been added for system identifiers (table names,
|
|
attribute names, etc.) This replaces the old char16 type. The
|
|
of name is set by the NAMEDATALEN #define in src/Makefile.global
|
|
* a readable reference manual that describes the query language.
|
|
* added host-based access control. A configuration file ($PGDATA/pg_hba)
|
|
is used to hold the configuration data. If host-based access control
|
|
is not desired, comment out HBA=1 in src/Makefile.global.
|
|
* changed regex handling to be uniform use of Henry Spencer's regex code
|
|
regardless of platform. The regex code is included in the distribution
|
|
* added functions and operators for case-insensitive regular expressions.
|
|
The operators are ~* and !~*.
|
|
* pg_dump uses COPY instead of SELECT loop for better performance
|
|
|
|
Bug fixes:
|
|
* fixed an optimizer bug that was causing core dumps when
|
|
functions calls were used in comparisons in the WHERE clause
|
|
* changed all uses of getuid to geteuid so that effective uids are used
|
|
* psql now returns non-zero status on errors when using -c
|
|
* applied public patches 1-14
|

Postgres95 1.0 Tue Sep 5 11:24:11 PDT 1995
|
|
=========================================================
|
|
|
|
Copyright change:
|
|
* The copyright of Postgres 1.0 has been loosened to be freely modifiable
|
|
and modifiable for any purpose. Please read the COPYRIGHT file.
|
|
Thanks to Professor Michael Stonebraker for making this possible.
|
|
|
|
Incompatibilities:
|
|
* date formats have to be MM-DD-YYYY (or DD-MM-YYYY if you're using
|
|
EUROPEAN STYLE). This follows SQL-92 specs.
|
|
* "delimiters" is now a keyword
|
|
|
|
Enhancements:
|
|
* sql LIKE syntax has been added
|
|
* copy command now takes an optional USING DELIMITER specification.
|
|
delimiters can be any single-character string.
|
|
* IRIX 5.3 port has been added.
|
|
Thanks to Paul Walmsley (ccshag@everest.cclabs.missouri.edu) and others.
|
|
* updated pg_dump to work with new libpq
|
|
* \d has been added psql
|
|
Thanks to Keith Parks (emkxp01@mtcc.demon.co.uk)
|
|
* regexp performance for architectures that use POSIX regex has been
|
|
improved due to caching of precompiled patterns.
|
|
Thanks to Alistair Crooks (agc@uts.amdahl.com)
|
|
* a new version of libpq++
|
|
Thanks to William Wanders (wwanders@sci.kun.nl)
|
|
|
|
Bug fixes:
|
|
* arbitrary userids can be specified in the createuser script
|
|
* \c to connect to other databases in psql now works.
|
|
* bad pg_proc entry for float4inc() is fixed
|
|
* users with usecreatedb field set can now create databases without
|
|
having to be usesuper
|
|
* remove access control entries when the entry no longer has any
|
|
permissions
|
|
* fixed non-portable datetimes implementation
|
|
* added kerberos flags to the src/backend/Makefile
|
|
* libpq now works with kerberos
|
|
* typographic errors in the user manual have been corrected.
|
|
* btrees with multiple index never worked, now we tell you they don't
|
|
work when you try to use them
|
|
|
|

Postgres95 Beta 0.03 Fri Jul 21 14:49:31 PDT 1995
|
|
=========================================================
|
|
Incompatible changes:
|
|
* BETA-0.3 IS INCOMPATIBLE WITH DATABASES CREATED WITH PREVIOUS VERSIONS
|
|
(due to system catalog changes and indexing structure changes).
|
|
* double-quote (") is deprecated as a quoting character for string literals;
|
|
you need to convert them to single quotes (').
|
|
* name of aggregates (eg. int4sum) are renamed in accordance with the
|
|
SQL standard (eg. sum).
|
|
* CHANGE ACL syntax is replaced by GRANT/REVOKE syntax.
|
|
* float literals (eg. 3.14) are now of type float4 (instead of float8 in
|
|
previous releases); you might have to do typecasting if you depend on it
|
|
being of type float8. If you neglect to do the typecasting and you assign
|
|
a float literal to a field of type float8, you may get incorrect values
|
|
stored!
|
|
* LIBPQ has been totally revamped so that frontend applications
|
|
can connect to multiple backends
|
|
* the usesysid field in pg_user has been changed from int2 to int4 to
|
|
allow wider range of Unix user ids.
|
|
* the netbsd/freebsd/bsd o/s ports have been consolidated into a
|
|
single BSD44_derived port. (thanks to Alistair Crooks)
|
|
|
|
SQL standard-compliance (the following details changes that makes postgres95
|
|
more compliant to the SQL-92 standard):
|
|
* the following SQL types are now built-in: smallint, int(eger), float, real,
|
|
char(N), varchar(N), date and time.
|
|
|
|
The following are aliases to existing postgres types:
|
|
smallint -> int2
|
|
integer, int -> int4
|
|
float, real -> float4
|
|
char(N) and varchar(N) are implemented as truncated text types. In
|
|
addition, char(N) does blank-padding.
|
|
* single-quote (') is used for quoting string literals; '' (in addition to
|
|
\') is supported as means of inserting a single quote in a string
|
|
* SQL standard aggregate names (MAX, MIN, AVG, SUM, COUNT) are used
|
|
(Also, aggregates can now be overloaded, i.e. you can define your
|
|
own MAX aggregate to take in a user-defined type.)
|
|
* CHANGE ACL removed. GRANT/REVOKE syntax added.
|
|
- Privileges can be given to a group using the "GROUP" keyword.
|
|
For example:
|
|
GRANT SELECT ON foobar TO GROUP my_group;
|
|
The keyword 'PUBLIC' is also supported to mean all users.
|
|
|
|
Privileges can only be granted or revoked to one user or group
|
|
at a time.
|
|
|
|
"WITH GRANT OPTION" is not supported. Only class owners can change
|
|
access control
|
|
- The default access control is to to grant users readonly access.
|
|
You must explicitly grant insert/update access to users. To change
|
|
this, modify the line in
|
|
src/backend/utils/acl.h
|
|
that defines ACL_WORLD_DEFAULT
|
|
|
|
Bug fixes:
|
|
* the bug where aggregates of empty tables were not run has been fixed. Now,
|
|
aggregates run on empty tables will return the initial conditions of the
|
|
aggregates. Thus, COUNT of an empty table will now properly return 0.
|
|
MAX/MIN of an empty table will return a tuple of value NULL.
|
|
* allow the use of \; inside the monitor
|
|
* the LISTEN/NOTIFY asynchronous notification mechanism now work
|
|
* NOTIFY in rule action bodies now work
|
|
* hash indices work, and access methods in general should perform better.
|
|
creation of large btree indices should be much faster. (thanks to Paul
|
|
Aoki)
|
|
|
|
Other changes and enhancements:
|
|
* addition of an EXPLAIN statement used for explaining the query execution
|
|
plan (eg. "EXPLAIN SELECT * FROM EMP" prints out the execution plan for
|
|
the query).
|
|
* WARN and NOTICE messages no longer have timestamps on them. To turn on
|
|
timestamps of error messages, uncomment the line in
|
|
src/backend/utils/elog.h:
|
|
/* define ELOG_TIMESTAMPS */
|
|
* On an access control violation, the message
|
|
"Either no such class or insufficient privilege"
|
|
will be given. This is the same message that is returned when
|
|
a class is not found. This dissuades non-privileged users from
|
|
guessing the existence of privileged classes.
|
|
* some additional system catalog changes have been made that are not
|
|
visible to the user.
|
|
|
|
libpgtcl changes:
|
|
* The -oid option has been added to the "pg_result" tcl command.
|
|
pg_result -oid returns oid of the last tuple inserted. If the
|
|
last command was not an INSERT, then pg_result -oid returns "".
|
|
* the large object interface is available as pg_lo* tcl commands:
|
|
pg_lo_open, pg_lo_close, pg_lo_creat, etc.
|
|
|
|
Portability enhancements and New Ports:
|
|
* flex/lex problems have been cleared up. Now, you should be able to use
|
|
flex instead of lex on any platforms. We no longer make assumptions of
|
|
what lexer you use based on the platform you use.
|
|
* The Linux-ELF port is now supported. Various configuration have been
|
|
tested: The following configuration is known to work:
|
|
kernel 1.2.10, gcc 2.6.3, libc 4.7.2, flex 2.5.2, bison 1.24
|
|
with everything in ELF format,
|
|
|
|
New utilities:
|
|
* ipcclean added to the distribution
|
|
ipcclean usually does not need to be run, but if your backend crashes
|
|
and leaves shared memory segments hanging around, ipcclean will
|
|
clean them up for you.
|
|
|
|
New documentation:
|
|
* the user manual has been revised and libpq documentation added.
|
|
|
|
|
|
|
|
Postgres95 Beta 0.02 Thu May 25 16:54:46 PDT 1995
|
|
=========================================================
|
|
Incompatible changes:
|
|
* The SQL statement for creating a database is 'CREATE DATABASE' instead
|
|
of 'CREATEDB'. Similarly, dropping a database is 'DROP DATABASE' instead
|
|
of 'DESTROYDB'. However, the names of the executables 'createdb' and
|
|
'destroydb' remain the same.
|
|
|
|
New tools:
|
|
* pgperl - a Perl (4.036) interface to Postgres95
|
|
* pg_dump - a utility for dumping out a postgres database into a
|
|
script file containing query commands. The script files are in a ASCII
|
|
format and can be used to reconstruct the database, even on other
|
|
machines and other architectures. (Also good for converting
|
|
a Postgres 4.2 database to Postgres95 database.)
|
|
|
|
The following ports have been incorporated into postgres95-beta-0.02:
|
|
* the NetBSD port by Alistair Crooks
|
|
* the AIX port by Mike Tung
|
|
* the Windows NT port by Jon Forrest (more stuff but not done yet)
|
|
* the Linux ELF port by Brian Gallew
|
|
|
|
The following bugs have been fixed in postgres95-beta-0.02:
|
|
* new lines not escaped in COPY OUT and problem with COPY OUT when first
|
|
attribute is a '.'
|
|
* cannot type return to use the default user id in createuser
|
|
* SELECT DISTINCT on big tables crashes
|
|
* Linux installation problems
|
|
* monitor doesn't allow use of 'localhost' as PGHOST
|
|
* psql core dumps when doing \c or \l
|
|
* the "pgtclsh" target missing from src/bin/pgtclsh/Makefile
|
|
* libpgtcl has a hard-wired default port number
|
|
* SELECT DISTINCT INTO TABLE hangs
|
|
* CREATE TYPE doesn't accept 'variable' as the internallength
|
|
* wrong result using more than 1 aggregate in a SELECT
