Thanks for testing!

This was broken as part of:
commit 87bb2ade2ce646083f39d5ab3e3307490211ad04

Convert Postgres arrays to Perl arrays on PL/perl input arguments
More generally, arrays are turned in Perl array references, and row and
composite types are turned into Perl hash references. This is done
recursively, in a way that's natural to every Perl programmer.
To avoid a backwards compatibility hit, the string representation of
each structure is also available if the function requests it.
Authors: Alexey Klyukin and Alex Hunsaker.
Some code cleanups by me.
Which also means it only breaks HEAD/9.1 (I did test and review 9.0 and down.)
Per
http://search.cpan.org/~jesse/perl-5.14.0/pod/perlguts.pod#AVs,_HVs_and_undefined_values,
we do not want to use &PL_sv_undef for undef values in hashes and
arrays. I (inadvertently) broke this in the above commit. As perldoc
mentions &PL_sv_undef seems like the intuitive thing to use. But its
wrong in certain cases.
We have 6 other uses of &PL_sv_undef, 2 &PL_sv_no and 1 &PL_sv_yes.
These are all ok as none of them use the HV/AV store interface.
I elected _not_ to add any regression tests. (If we forget about this
in the future, it will likely be in other code paths). Instead I added
comments to the places that used &PL_sv_undef noting that we
explicitly avoid it on purpose.
