The author of this bug was good enough to send me a copy, since I don't normally read the -bugs list. It can now be found at http://archives.postgresql.org/pgsql-bugs/2007-01/msg00111.php .
I dug into it a bit and found that pltcl and plpython appear to use almost identical code, but only pltcl has this limitation documented. I'm inclined to say we should document this for plperl and plpython for stable releases and remove the limitation for all three for 8.3. I see that SQL level prepare calls regprocin() to resolve type names, so maybe we should that for the PLs when calling SPI_prepare as well. Alternatively, should we adjust things lower down (e.g. in typenameType() or LookupTypeName() ) ?
