It's basically logging anything that changes the structure of the database. It would be easy enough to grep out what you do and don't want later. > Martin French is right though, ask your developers to write down all their > SQL struct changes and they look at you funny... and being a developer > myself I'd look at me funny.

I've worked in three different shops now as a dev-dba and sysadmin, and in all three, all DDL changes had to be committed and / or handed over to the DBAs. period. Look funny all they want, they either give up the DDL or their code doesn't get pushed off dev servers onto anything else. At the very least they should be able to tell you which tables changed to go with which code changes, or you're not sure what code you can and can't push. I get both of your point on this, but it's a discipline issue that needs sorting out with the developers if you want to have reproduceable ddl changes in all your systems that match the code changes. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
