Re: [Plperlng-devel] strange bug in plperl

Thanks. I have 2 questions regarding this.

1. Is prodesc->fn_retistuple true if and only if this is a set returning
function? (what about setof int? what about a function returning a single
composite?)

2. I am suspicious about the use of these globals to stash data (and they
should all be marked static in any case so we don't pollute the namespace)
and already have it on my TODO list to examine them more closely. Won't they
get clobbered if our function makes an spi call which in turn calls this or
another perl function? If they will, we might need to use some sort of very
simple stack structure for this data, up to some reasonable level of
recursion (any bids?).

cheers
