While checking our server, I noticed quite a few files in the pg_clog directory.
These files date from today back to the day when I installed PostgreSQL.
Is there a maintenance task which can be run to purge the files which are no longer needed?
I assume the majority of them are not needed, since the data has already been commited.
I back up nightly with pg_dump, but this obviously does not reset these files.
Do I need to do a backup with archiving in order to clear these out?
TIA,
Benjamin
