Обсуждение: Anyone know of a Schema Comparer
Hi,
We will have anything upto 400 schema in our db. Each Schema is a replica of a “master” schema. Can anyone recommend a tool that we can compare our master schema to any given target schema which will then generate an update script which can subsequently be executed ? We have looked at EMS comparer and few others but all seem to compare one entire db with another.
Regards
Paul Newman

EMS DB comparer has this limitation, but it's probably the best tool out there. We solved it be wrapping the command line version in a little script, that dumps the DDL (no data) of the two schemas and loads them into a sync_from and sync_to database. Not pretty, but works well. -- Regards, Hannes Dorbath
Hi Paul, why not simply pg_dump your database and then restore only the chosen schema on 2 new databases ? Then you can use your software comparers. Making a script that dump and restore only the chosen schemas should be 3 lines shell script.
