If we are envisioning that the function might emit multiple warnings
per call, a useful definition could be to return the number of
warnings (so zero is good, not-zero is bad).  But I'm not sure that's
really better than a boolean result.  pg_dump/pg_restore won't notice
anyway, but perhaps other programs using these functions would care.
