Ah. Looks like the has_column_privilege stuff is incautious about whether
it's handed a valid table OID:
regression=# select has_column_privilege(42::oid, 'z'::text, 'q'::text);
server closed the connection unexpectedly
In older branches I get
regression=# select has_column_privilege(42::oid, 'z'::text, 'q'::text);
ERROR: column "z" of relation "(null)" does not exist
but that's only because glibc's snprintf is forgiving about getting a
NULL pointer for %s. On some other platforms it'd end in SIGSEGV.
Will fix, thanks for report!
