I'm trying to migrate a PostgreSql 8.3 database from a Windows 2003 server to a PostgreSql 8.4 Linux x86_64 server running Ubuntu Server 12.04. When running pg_dump from the Linux server, I get: postgres@ubuntupostgresql:~$ pg_dump -h 192.168.10.105 -U postgres ris pg_dump: SQL command failed pg_dump: Error message from server: ERROR: unrecognized configuration parameter "synchronize_seqscans" pg_dump: The command was: SET synchronize_seqscans TO off I've read in older mails that this massage shows when one side is running EnterpriseDB version of PostgreSql and the other is running a PostgreSql version. I must point out this is not my case, both sides are running PostgreSql versions, the Linux side is running the one from the official repository, and the Windows one is running an old 8.3 version downloaded from postgresql.org. Any hint?. Regards, -- Leonardo M. Ramé Medical IT - Griensu S.A. Av. Colón 636 - Piso 8 Of.
