There should be at most 2*checkpoint_segments+1 files in pg_xlog, which
are 16MB each. So you shouldn't be having a problem.

If there are more than this, it could be because you have
currently/previously had archive_command set and the archive command
failed to execute correctly, or the database was shutdown/crashed prior
to the archive commands being executed.

IIRC there was a bug that allowed this to happen, but that was some time
ago.

Perhaps you could show us the dir listing, so we can check that there is
not a new problem emerging? Can you also show us the contents of the
pg_xlog/archive_status directory? Thanks.
