adding it as already-imported module should not be hard 

I think that moving to saner mappings should at least be discussed

and even if it is not in scope for the user-defined function body there
is nothing that prevents one from using it for conversion.

The Decimal _type_ needs not to be in scope for using Decimal
_instances_

maybe this should/could be controlled by a GUC.



btw, can we currently use funtions in setting GUC parameters ?

if we can , then we could define some python environment initializing
function and then do

ALTER USER xxx SET pyinit = initialise_python_for_xxx()
