AFAIK, there is nothing that requires pl/perl, pl/tcl or pl/python to be
in core either.

Actually, I think that being an independent language / postgresql
extension tool, pl/proxy is _more_ fit to be in core than external
language adapters.

And it would be nice, if some well-maintained sample language (pl/sh or
even pl/dummy) which serves as a sample of latest ways to make use of
pl/function support in core pg code would be included in core as well.

with some slight restructuring (separation of pl-clue and actrual
cacheing/execution) pl/proxy could serve this space as well

Not silly at all.

Tsearch in core seems a wise choice, as well as _some_ implementation of
multiple locales.

Usually it is also a way of getting the _core_ better/more functional.

As mentioned in another mail, we don't _need_ other pl-s (except maybe
pl/pgsql) to be in core either.

And it is an additional bonus for consultants, if we keep some of the
best parts separate ;)

PS. Thinking more of it, I don't even understand, what it means for a
PL to be "in core" ;)

Are they are under src/pl just for the reason that there is not
contrib/pl ?

Does pushing something into core give impression of trying to get rid of
the responsibility of managing that piece of code ?
