I've inherited two postgres databases, a master and a backup, on different machines (on same subnet). I need to verify the backup is complete. There are 60 tables, all under 50,000 rows except for 5 tables with 100M+ rows.

It takes 2 hours to dump a backup, a week to load, so just doing a backup isn't an option. (yet)

I'm thinking of using Perl to do brute force comparisons of the small tables. I can automate column named selects based on the schema docs, and fill a hash based on the table keys with the master data, and compare that to the backup content. I may have to use a cursor, and it may be slow, but it's all I can think of. But I think this will be insane on the big tables.

Has anyone an idea of a better method of attack?
