I think this is because the handler function is in the pg_catalog
schema, which aren't dumped. However, it seems they need to be if a
non-pg_catalog language is created that uses them.
This seems odd though:
/* Skip if not to be dumped */
if (!plang->dobj.dump || dopt->dataOnly)
funcInfo = findFuncByOid(plang->lanplcallfoid);
if (funcInfo != NULL && !funcInfo->dobj.dump && plang->dobj.dump)
funcInfo = NULL; /* treat not-dumped same as not-found */
The reason I think it's odd is because, if it finds that the language
needs to be dumped, it checks whether the functions referenced for the
handler, inline and validator are in the pg_catalog schema too. If
they are, it doesn't output them, but if we know the language isn't in
pg_catalog, and the functions for these options are, then surely we
*have* to output them? Should there be any checks for these functions
