Each language handler is free to interpret the source text in its own way.
This has nothing to do with trustedness (is SQL not trusted?). Neither
PL/pgSQL nor PL/Tcl involve a compilation step, although PL/pgSQL does
some optimizations internally that could be called compilation.
Is this question just out of random interest, or are you really asking
something like are functions fast?
