To me this seems to be a little like the much-disputed notice for adding
implicit range-table entries:  Either it's an error, then you abort, or
it's legal, then you leave the user alone and perhaps explain failure
scenarios in the documentation.  At least until we have something like a
user-configurable warning level.

elog(DEBUG) might be okay, but only with a positive DebugLvl, IMHO.
