Attached is a first version for the "CREATE OR REPLACE LANGUAGE" patch.
It's still missing some functionality (especially the update part is
far away from being complete) and it's also missing documentation.
I just want to know if i'm heading in the right direction or if
something is totally broken in my basic approach:
In case a language is already in pg_pltemplate, the (possibly changed)
values from this table are used to update the pg_languages entry. This
gives the ability to change the owner, trust status, the language or
In case the language is not in pg_pltemplate, the values from the
commandline are used, just like "create language".
Thanks & kind regards
