Ja, it's right on the top, but long gone by now…

This sounds like it should work to capture more context when the
Assertion fails the next time.  I have to purge the catalogs a bit
though to avoid stopping early on boring core dumps.  Most of them are
currently caused by acl.c using text for syscache lookups and triggering
an NAMEDATALEN assertion.

E.g.: select has_language_privilege('smithsmithsmithsmithsmithsmithsmithsmithsmithsmithsmithsmithsmith', smith');
