I used to work on a patch that converts postgres arrays into perl array
references:
http://archives.postgresql.org/pgsql-hackers/2009-11/msg01552.php
I have a newer patch, which is, however, limited to one-dimensional resulting
arrays. If there's an interest in that approach I can update it for the
current code base, add support multi-dimensional arrays (I used to implement
that, but lost the changes accidentally) and post it for review.
