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 -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!
