Thank you very much for sharing your real-time experience.
Do you think that this "significantly bloated system catalogs" is caused
because of the old version 8.2.3 we're running? Will this be resolved in
latest PostgreSQL v9.0? BTW, what version of PostgreSQL are you handling?
Doc says: " Temporary tables are automatically dropped at the end of a
session, or optionally at the end of the current transaction (see ON COMMIT
below). Any indexes created on a temporary table are automatically temporary
as well."
If temporary tables and its indexes are automatically dropped at the end of
the session, why would it cause bloat in system catalogs? I hope you can
make me understand by sharing your real-time experience.
Again, thanks for your advice.
