A DBA is allowed to create a language in his database if it's marked "tmpldbacreate" in pg_pltemplate. The factory default is that this is set for all standard trusted languages, but of course a superuser may adjust the settings. In service of this, add the long-foreseen owner column to pg_language; renaming, dropping, and altering owner of a PL now follow normal ownership rules instead of being superuser-only. Jeremy Drake, with some editorialization by Tom Lane.
