Hm, Postgres doesn't support comma-for-decimal-point in very many
contexts, so I'm wondering exactly what your queries are like.
If that usage only appears in strings that are processed with
to_number() and a D format character, then maybe you can make this
work, but that seems pretty restrictive.

Sure. See lc_numeric.
