Postgres database search all tables

Question

Good Afternoon everyone, I've got a knotty problem, I have a mature Postgres database that has over 500 tables, and is too large to dump. When a product is added to the database a new line is created in many tables and I'd like to check what information is added in order to replicate the functionality in a new piece of software. The reason is the existing software interface is very old and unfriendly so we are replacing it. I can't very easily use the approach suggested here: Search entire postgres database? . Can anyone suggest another solution?

I should clarify i can't modify the database at all, until we have reliably replaced the existing interface and that won't be for months yet.

Thanks

You can set log_statement = 'all' for the short time when you run your experiment. Make sure that your log_line_prefix contains %c . Then you can track all SQL statements that belong to one database session.
