There is no way to have one plperl function call another directly - they
are anonymous and a reference to them is not stored anywhere accessible
inside the perl interpreter. The only place the reference is stored is
in a table on the C side of the plperl glue code.
This is an architectural limitation that is not easily overcome.
Back to the original suggestion - I would like to have a lot more magic
that maps between perl hashrefs and postgres composites, and between
perl arrayrefs and postgres arrays. A plperl programmer should ideally
never have to construct or deconstruct the text representation of an
array or a composite. That will have to be looked at after this release
- we only just hit the feature freeze cutoff with what we have now,
which is why a few warts are coming to light.
