You mean for implementing stored procedures?
I'd say that the answer varies depending on what the stored proc is
for.
- If it needs to do "text munging," then one of {Perl|Python|Tcl} seem
appropriate; they draw in big libraries of text munging code
- If you're writing code that selects data from various tables based
on the inputs, then pl/pgsql tends to be the natural answer
- C is needed when you need deep engine access that can't be gotten
any other way
- Untrusted Perl/Tcl are nifty if you need access to the rich sets of
external libraries
- If you have some code in Java that you'd want to run in the DB
server, then one of the pl/Java systems may be for you
It doesn't seem overly flameworthy to me.
Except for the cases where you *must* use C, you can usually
accomplish things in the "wrong" language, but there are likely to be
drawbacks...
- Doing funky string munging using the SQL functions available in
pl/pgsql is likely to be painful;
- Doing a lot of DB manipulation in pl/Perl or pl/Tcl or such
requires having an extra level of function manipulations that
won't be as natural as straight pl/pgsql.

Q: Are the SETQ expressions used only for numerics?
A: No, they can also be used with symbolics (Fig.18).
