The code relies on SELECT queries now to fetch a list of relation
OIDs and it is read-only. If it happens that another query type makes
sense for this code path, then the person using the routine will need
to think about what to do when seeing the new error. The current code
exists for ages, so I have applied your change only on HEAD.
