[SQL] Which procedural language to use for functions.

[Saltsgaver, Scott]

Which procedural language is best for writing PostgreSQL functions:
'PL/pgSQL', 'PL/perl', or 'PL/Tcl'?  

I know that I can't do table creates in 'PL/pgSQL'?  

Is there an obvious choice as far speed and size?

Thanks,
Scott Saltsgaver
