One language isn't more "native" than another, really. SQL is a bit more native in the sense that it might be inlined, and C is more native in the sense that it is native code. But PL/pgSQL just happens to be a good language when you are doing mostly SQL with some procedural aspects, it doesn't really have an inherent performance advantage over external PLs. There may be some implementation quality differences, however. > If I'm executing say a PL/Perl procedure, once I've executed it the first > time, can I take it the interpreter is now resident withing the PG footprint? Yes. Regards, Jeff Davis
