Is there a clean way to dump/restore a single table which contains large
objects instead of the entire DB?
In Pg version=7.4 -
pg_dump: Large object output is not supported for a single table.
pg_dump: Use all tables or a full dump instead.
Does version 8.0's pg_dump support a single table dump
Does large object table space is associated with the table (with oid)'s
table space created? If not, what's about table with bytea column?
Thanks.

TIP 2: you can get off all lists at once with the unregister command
If speed (add/get) is the only concern, image files could be big (~10M),
and database only serves as storage. In the postgresql 8, which type
(bytea vs large object) is the preferred one? Is it true, in general,
that bytea inserts is slower?
Thanks.

My guess is that one
We upgraded from 7.2 to 7.4, it looks like
everything working, but when I issue a query such as select * from tab (tab has
about 2-3 million records), it causes core dump. I tuned some the parameters,
it still produce the core.
Thanks for any hints.

How to build some of those contrib? Can you add one of contrib on the
existing Postgresql without reconfigure, rebuild, and reinstall?
Thanks.

The original simple SQL -

This is not simple, it is broken SQL

at least. But when I use PostgreSQL, I need find an alternative solution to
handle such issue.

Sorry, the query you provided works in Pg, my mistake :!
select atcode from table group by atcode order by max(torder);
