This migration requires a complete dump of the 6.2 or 6.2.1 database and a
|
||||
restore of the database in 6.3.
|
||||
|
||||
In addition, 6.3 has separate permissions for views, rather than relying
|
||||
on the permissions set on the underlying tables. For this reason, you will
|
||||
have to set permissions on your views if you want anything but the default
|
||||
permissions.
|
||||
There are some general 6.3 issues that I want to mention. These are
|
||||
only the big items that can not be described in one sentence. A review
|
||||
of the HISTORY files is still needed.
|
||||
|
||||
6.3 has had its default permissions on a table set such that unless you
|
||||
are the owner, when a table is created, other users of the system won't
|
||||
have access to them. You *must* do a 'GRANT' for each table you wish open
|
||||
to other ppl.
|
||||
First, we now have subselects. Now that we have them, I would like to
|
||||
mention that without subselects, SQL is a very limited language.
|
||||
Subselects are a major feature, and you should review your code for
|
||||
places where subselects provide a better solution for your queries. I
|
||||
think you will find that there are more uses for subselects than you may
|
||||
think. Vadim has put us on the big SQL map with subselects, and fully
|
||||
functional ones too. The only thing you can't do with subselects is to
|
||||
use them in the target list.
|
||||
|
||||
Those migrating from earlier 1.* releases should first upgrade to 1.09
|
||||
because the COPY output format was improved from the 1.02 release.
|
||||
Second, 6.3 uses unix domain sockets rather than TCP/IP by default. To
|
||||
enable connections from other machines, you have to use the new
|
||||
postmaster -i option, and of course edit pg_hba.conf. Also, for this
|
||||
reason, the format of pg_hba.conf has changed.
|
||||
|
||||
Third, char() fields will now allow faster access than varchar() or
|
||||
text. Specifically, the text and varchar() have a penalty for access to
|
||||
any columns after the first column of this type. char() used to also
|
||||
have this access penalty, but it no longer does. This may suggest that
|
||||
you redesign some of your tables, especially if you have short character
|
||||
columns that you have defined as varchar() or text. This and other
|
||||
changes make 6.3 even faster than earlier releases.
|
||||
|
||||
We now have passwords definable independent of any Unix file. There are
|
||||
new SQL USER commands. See the pg_hba.conf manual page for more
|
||||
information. There is a new table, pg_shadow, which is used to store
|
||||
user information and user passwords, and it by default only SELECT-able
|
||||
by the postgres super-user. pg_user is now a view of pg_shadow, and is
|
||||
SELECT-able by PUBLIC. You should keep using pg_user in your
|
||||
application without changes.
|
||||
|
||||
User-created tables now no longer have SELECT permission to PUBLIC by
|
||||
default. This was done because the ANSI standard requires it. You can
|
||||
of course GRANT any permissions you want after the table is created.
|
||||
System tables continue to be SELECT-able by PUBLIC.
|
||||
|
||||
We also have real deadlock detection code. No more sixty-second
|
||||
timeouts. And the new locking code implements a FIFO better, so there
|
||||
should be less resource starvation during heavy use. For performance
|
||||
reasons, time travel is gone, but can be implemented using triggers (see
|
||||
pgsql/contrib/spi/README). Please check out the new \d command for
|
||||
types, operators, etc. Also, views have their own permissions now, not
|
||||
based on the underlying tables, so permissions on them have to be set
|
||||
separately. Check /pgsql/interfaces for some new ways to talk to
|
||||
PostgreSQL.
|
||||
|
||||
This is the first release that really required an explaination for
|
||||
existing users. In many ways, this was necessary because the new
|
||||
release removes many limitations, and the work-arounds people were using
|
||||
are no longer needed.
|
||||
|
||||
Long live PostgreSQL.
