yes it would, if you were using something other than postgres for

you should use the "Null" locker for postgres, since the postgres
store does its own locking (using postgres transactions).

set the DBI_TRACE environment variable to /tmp/dbi.log (or something),
then start apache.  all DBI calls should now log several lines to that

in there somewhere will be the actual SQL statement being used, which
should give some clues as to whats going wrong.
