Here is a new migratoin file for 1.02.1. It includes the 'copy' change
|
||||
and a script to convert old ascii files.
|
||||
|
||||
---------------------------------------------------------------------------
|
||||
|
||||
The following notes are for the benefit of users who want to migrate
|
||||
databases from postgres95 1.01 and 1.02 to postgres95 1.02.1.
|
||||
|
||||
If you are starting afresh with postgres95 1.02.1 and do not need
|
||||
to migrate old databases, you do not need to read any further.
|
||||
|
||||
----------------------------------------------------------------------
|
||||
|
||||
In order to upgrade older postgres95 version 1.01 or 1.02 databases to
|
||||
version 1.02.1, the following steps are required:
|
||||
|
||||
1) start up a new 1.02.1 postmaster
|
||||
|
||||
2) Add the new built-in functions and operators of 1.02.1 to 1.01 or 1.02
|
||||
databases. This is done by running the new 1.02.1 server against
|
||||
your own 1.01 or 1.02 database and applying the queries attached at
|
||||
the end of thie file. This can be done easily through psql. If your
|
||||
1.01 or 1.02 database is named "testdb" and you have cut the commands
|
||||
from the end of this file and saved them in addfunc.sql:
|
||||
|
||||
% psql testdb -f addfunc.sql
|
||||
|
||||
Those upgrading 1.02 databases will get a warning when executing the
|
||||
last two statements because they are already present in 1.02. This is
|
||||
not a cause for concern.
|
||||
|
||||
* * *
|
||||
|
||||
If you are trying to reload a pg_dump or text-mode 'copy tablename to
|
||||
stdout' generated with a previous version, you will need to run the
|
||||
attached sed script on the ASCII file before loading it into the
|
||||
database. The old format used '.' as end-of-data, while '\.' is now the
|
||||
end-of-data marker. Also, empty strings are now loaded in as '' rather
|
||||
than NULL. See the copy manual page for full details.
|
||||
|
||||
sed 's/^\.$/\\./g' <in_file >out_file
|
||||
|
||||
If you are loading an older binary copy or non-stdout copy, there is no
|
||||
end-of-data character, and hence no conversion necessary.

||||

The following notes are for the benefit of users who want to migrate
|
||||
databases from postgres95 1.0 to postgres95 1.01.
|
||||
|
||||
If you are starting afresh with postgres95 1.01 and do not need
|
||||
to migrate old databases, you do not need to read any further.
|
||||
|
||||
----------------------------------------------------------------------
|
||||
|
||||
In order to postgres95 version 1.01 with databases created with
|
||||
postgres95 version 1.0, the following steps are required:
|
||||
|
||||
1) Set the definition of NAMEDATALEN in src/Makefile.global to 16
|
||||
and OIDNAMELEN to 20.
|
||||
|
||||
2) Decide whether you want to use Host based authentication.
|
||||
|
||||
A) If you do, you must create a file name "pg_hba" in your top-level data
|
||||
directory (typically the value of your $PGDATA). src/libpq/pg_hba
|
||||
shows an example syntax.
|
||||
|
||||
B) If you do not want host-based authentication, you can comment out
|
||||
the line
|
||||
HBA = 1
|
||||
in src/Makefile.global
|
||||
|
||||
Note that host-based authentication is turned on by default, and if
|
||||
you do not take steps A or B above, the out-of-the-box 1.01 will
|
||||
not allow you to connect to 1.0 databases.
|
||||
|
||||
3) compile and install 1.01, but DO NOT do the initdb step.
|
||||
|
||||
4) before doing anything else, terminate your 1.0 postmaster, and
|
||||
backup your existing $PGDATA directory.
|
||||
|
||||
5) set your PGDATA environment variable to your 1.0 databases, but set up
|
||||
path up so that 1.01 binaries are being used.
|
||||
|
||||
6) modify the file $PGDATA/PG_VERSION from 5.0 to 5.1
|
||||
|
||||
7) start up a new 1.01 postmaster
|
||||
|
||||
5) Add the new built-in functions and operators of 1.01 to 1.0
|
||||
databases. This is done by running the new 1.01 server against
|
||||
your own 1.0 database and applying the queries attached and saving
|
||||
in the file 1.0_to_1.01.sql. This can be done easily through psql.
|
||||
If your 1.0 database is name "testdb":
|
||||
|
||||
% psql testdb -f 1.0_to_1.01.sql

||||

||||
