No \d option. But can get it from pg_rules system view. It contains the

Hi,
In the first place, do we have any document which list the points to be
considered while upgrading to 7.3.2, other than HISTORY and
http://www.ca.postgresql.org/docs/momjian/upgrade_tips_7.3 ?
Since in 7.3.2 the default timestamp is without timezone, the below
command fails:
# CREATE TABLE
> work=# ALTER TABLE rdu ADD CONSTRAINT rdu_finish_time CHECK ((start_time <=
> finish_time) OR finish_time IS NULL);
> ERROR: AlterTableAddConstraint: rejected due to CHECK constraint
> rdu_finish_time
I can say that the field, finish_time have the values which conflict with
the check constrai

Add a timestamp field and set the default value as now(). If you wish to
maintain similar value during update, a before trigger could help.

Locate the file plperl.so and create the language with appropriate -L

Hi,
This is my second post.
I am using postgresql 7.3.2 on redhat linux 7.3.
Where does postgresql store tg_op and tg_when details for a trigger? If i
am right, it is not in pg_trigger catalog.
TIA.

pg_class for tables.
pg_attribute for columns.

You should have used --enable-multibyte option during configure. If you
had, you can use 'pg_config --configure' to ensure it.

I suppose, you have installed it from binary rpm. By default, packages

Version? ~/.pgpass is supported since 7.3. Two more solutions are:
1) Set PGPASSWORD variable to avoid pg_dump asking for password
2) Set connection as trust in pg_hba.conf

pg_dumpall is a good partner. If i am correct, you can also copy the
entire data directory, provided if both versions are same.

IMO, in 7.3.4, these two scripts (createuser & dropuser) preserve the
case by default even without double quote. For example, 'createuser
Admin' makes an entry Admin(not admin) in pg_shadow. Similarly, dropuser
deletes the same entry even with

No such built-in feature is available. But, we can write a before
trigger on update event to set the modified time.

drop column feature is implemented since 7.3. So, you please check out
your version.
