There are least 10 Procedural Languages <http://en.wikipedia.org/wiki/PL/pgSQL> available for PostGreSQL. The one that comes with the installation is PL/pgSQL. Which ones do you use and why?
I've often wondered how these "external" languages perform, figuring that using a native language would perform better. 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? Is it analogous to say Apache and mod_perl? The module/library has been loaded and is now ready? Or is it more along the lines of the one single PL/perl function is now cached, and any other function executed afterward will need to be brought in but the cached procedure is now "in ram"? Or.. is the function code just passed off to the system in a new process? I.e.. how do these hooks work?
