Well, plpgsql has the merit that its operations and control structures
are directly oriented towards "database stuff," so there's no need to
(for instance) invoke functions (e.g. - running queries via
spi_exec(), spi_query(), ...) in order to perform database
operations.
One of the salutory effects is that there is a pl/pgsql debugger that
can automatically handle things like single-stepping, and it does not
need to be aware of any Perl/Python internals.
