Hello,
we have a strange problem with a server instance:
PostgreSQL 8.2.11 on i486-pc-linux-gnu, compiled by GCC cc (GCC) 4.1.3 20070929
(prerelease) (Ubuntu 4.1.2-16ubuntu2)
It's one of several clones (server/system) where one of our applications cannot
work with a specific database restored from a dump of a database on a 8.2.18
server and created with the server's binaries. Recreating the database with
template0 again and doing a new restore didn't help. There are no error
messages during backup/restore.
The same database/app works fine on the other clones.
The same app works fine after we put the database on a different instance. So
it seems to be a specific problem with this server instance. Other databases on
this instance seem to work fine though.
During 'start up' the application does a couple of SELECTs on pg_catalog:
.
.
.
SELECT COUNT(*) FROM pg_attribute JOIN pg_type ON
pg_attribute.atttypid=pg_type.oid LEFT OUTER JOIN pg_attrdef ON (
pg_attribute.attnum=pg_attrdef.adnum AND
pg_attribute.attrelid=pg_attrdef.adrelid ) WHERE pg_attribute.attrelid =
2147483647 AND pg_attribute.attnum >= 0 AND pg_attribute.attisdropped = 'false'
.
.
.
It seems that the application doesn't find some rows. There are no error
messages in the server's log though.
The only two obvious differences we found are:
1. The superuser 'nutzer' used for the session had been given two roles
('nutzerrolle' and 'nutzeradmin') in the problematic server instance:
CREATE ROLE nutzerrolle
NOSUPERUSER INHERIT NOCREATEDB NOCREATEROLE;
CREATE ROLE nutzeradmin
SUPERUSER INHERIT CREATEDB CREATEROLE;
UPDATE pg_authid SET rolcatupdate=true WHERE OID=9413195::oid;
CREATE ROLE nutzer LOGIN
ENCRYPTED PASSWORD 'xxxx'
SUPERUSER INHERIT CREATEDB CREATEROLE;
UPDATE pg_authid SET rolcatupdate=true WHERE OID=2147483647::oid;
Removing these group memberships didn't help though. Recreating the user didn't
help neither.
2. Very high system OIDs - e.g. pg_attribute.attrelid max 3318384368 where
another server had max 94363332. The application connects via psqlODBC
(8.4.200).
Is this maybe a known problem?
Could you tell me, please?
Thank you very much,
Peter
