I was as surprised as you. It may have been the result of migrations
from older versions of RT to newer versions. We started at 3.2, are
currently running 3.4.5, and are preparing to migrate to 3.6.x. If
the OIDs are not needed, I would like to drop them in our migration
to 3.6.x. This is with an older version of searchbuilder (1.36) on
the 3.4.5 system. We could not upgrade to a newer version because it
caused our DB queries to fail. Do you think that it is safe to remove
the oid column?
