Re: "dumpProcLangs(): handler procedure for language

Thanks again for your input.  I think you're right about the OID's.

Watching the query logs, the pg_dump failed just after:
021210.00:58:25.578 [25527] query: SELECT * FROM pg_language WHERE
lanispl ORDER BY oid



MYDB=> select * from pg_language where lanispl order by oid;
 lanname | lanispl | lanpltrusted | lanplcallfoid | lancompiler
---------+---------+--------------+---------------+-------------
 plpgsql | t       | t            |   -1983262688 | PL/pgSQL
(1 row)

MYDB=> select oid from pg_proc where proname = 'plpgsql_call_handler';
     oid
-------------
 -1983262688
(1 row)

lifeaudioV2=> select * from pg_language where lanplcallfoid =
-1983262688;
 lanname | lanispl | lanpltrusted | lanplcallfoid | lancompiler
---------+---------+--------------+---------------+-------------
(0 rows)

MYDB=>


So yes, it looks like the OID's got messed up.  That negative number
looks suspiciously like an overflow on a max int.  Is there *any* way to
fix this, or should I just deal with it and upgrade?

BTW, does this mean that other data in the system could be corrupted?

If an upgrade is the best way out, are there any particular versions
that would a) fix the problem and b) allow for a clean transition?

I'm using Perl's DBI::Pg, PHP's pgsql extensions, and JDBC for
postgres... Just a bit weary of making transitions :-)  I understand
I'll have to perform a pg_dump for the transition to work, which I can
do by turning off the triggers, for now.


Thank you, Tom, for all your help.
