Re: [ADMIN] Merging two databases
Hi, Obviously it will always depends on the constraints in your schema, but why do not dump the databases out and import it into a single one properly? Once you get the new database, it should be easy to catch up with the 2 databases before the switching (with statements like insert/update into Newdb tables ...(select from Olddb tables)). It is up to you, this is to avoid replication settings, however using replication could be a good thing for future replication experiences. A.A.

I think you'll want Bucardo or Slony-I for this. You certainly can't do it with the built-in replication. -- Craig Ringer -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
