plperl exception catching

[Marc Evans <Marc@xxxxxxxxxxxxxxxxxxx>]

Hi -

Is it accurate for me to believe that there is no way to catch exception 
within plperl? For example, if an update fails, I'd like to do an insert. 
Yes, this is trivial to do in plpgsql, but sadly plpgsql is not usable due 
to not supporting variable variables. If plperl can't catch exceptions, is 
there a language that can be used?

Thanks in advance - Marc
