Обсуждение: pg_catalog.pg_roles DESTROYED?

I'm preparing to upgrade a 7.4.7 DB to 8.2.4.
I just got connectivity from new to old (different hosts), and being
a newhire and no-one had ever done any maintenance on the old DB, I
connected as joe-user to the old DB using the client of the new.
(joe-user is the owner of the DB)

I  did some analyze and vacuum-ing on two tables.
The last thing I did there was
 >vacuum full verbose tablename;
I did it twice to see the differing results.
It was HUGE and now is smaller.

I next tried to do a \dt and suddenly....

    airburst=> \dt
    ERROR:  relation "pg_catalog.pg_roles" does not exist

None of the \d - commands work.

Only if I go in as PG super can I avoid that error.  (Going in
locally after logging into that box.)

I'm new to PG myself, so I'd appreciate it if I had some hand-holding.

Thank you!

Which version of psql were you using?  psql doesn't really have good
support for backslash commands where the server and client are of mixed
versions -- for example, an 8.2.x psql will look for system tables that
didn't exist in 7.4.x.

Sounds like you're using a newer version of psql to connect to the older
host.

psql 8.2.4 would throw up errors like that when connecting to a 7.4.7 box -
when you login to the old box, then run psql, you would be running the old
version of psql and hence the error disappears.

Cheers,

======================
A big sigh of relief!
Actually on the way home last night I thought I ought to try as joe-
user locally on that box, but your (plural) comments were nice to
read before I got here to test it out myself.

Thank you both,
Ralph
