Re: [ADMIN] Postgres schema comparison.

Stef,

I use dblink to attach to both databases and query pg_namespace, pg_class, pg_attribute ... to get the diffs. See
attached as an example. look for the dblink_connect lines to specify your database. You will need to install
contrib/dblink. I used this with 7.4.X series and have NOT tested yet with 8.0.X.

You can adjust the output to fit your needs.
