I *think* it can be changed with just a reload, but I'm not 100% sure. Check your logs after doing the reload, it'll complain if it isn't able to change that parameter on reload. 20m sounds reasonable, still would recommend compressing the WALs if they're likely to be less than full (less than 16M of data in 20m). > 2.

This is the default, so unless you changed the default, yes, it's already running. > 3. Run VACUUM FREEZE ANALYZE since bulk loading was done earlier. (Can this > be done while the db is active and on production?) Yes, you can freeze records while the DB is running (erm, I don't know that you can run it w/o the DB running..). I don't know that I'd jump to running it right away though, unless you know that you need it...? > All 3 steps is to lower the WAL files that are being shipped out.

You probably just need to change archive_timeout and reload the database. Well, you also need to go read the documentation, but that's beside the point. > Please assist. Uhm, pretty sure I have been?
