Yes. The functions you create in Pg become regular functions you can
call. It's all the same to the client which language they're implemented
in.

I don't know how practical that would be, but Haskell has Pg
connectivity, and there's this thing called HDBC

 http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HDBC

I suppose you could write your functions in Haskell, and then use
Haskell/C connectivity to call the functions from Bond.
