Обсуждение: copying databases
i have created a DB on one server using postgresql 6.5.3 and now i need to move this DB to a machine running the postgresql 6.3 release (theone shipped with debian slink). I'd like to know how to move the DB from one server to the other and eventually if there are any incompatibility passing from the new release to a older one.

The simplest solution is 'pg_dump BASE' on one machine and 'psql -f FILE BASE' on the other. It frees you from Postgres'versions. [The only problem I know is if you use BLOBs.]

Chances are you won't have much luck though, since what 6.5.3's pg_dump creates is generally only intended for later releases. Software is generally not optimized for downgrading. ;) -- Peter Eisentraut Sernanders väg 10:115 peter_e@gmx.net 75262 Uppsala http://yi.org/peter-e/ Sweden
