PostgreSQL takes care of this itself. I don't know where it is
documented but IIRC from old messages, the number of files in pg_xlog
should level out at about two-times your checkpoint_settings value.
I'd have to do some digging as I don't recall for sure, but I think that
if you are using archive_command setting to archive WAL files the
archive command does not return "success", then the WAL file will not be
removed/reused.
Cheers,
Steve
