I'm not sure what happens with SQL, I think it's just stored as text.

PL/pgSQL is parsed and stored as a parse tree for execution.  Perl
does basically the same thing IIRC, and Python compiles to byte-code.
I'm not sure about TCL...

Let us cross over the river, and rest under the shade of the trees.
