I'm planning to work with Andrew Dunstan on some enhancements to PL/Perl
for PostgreSQL 8.5.
I've written up some initial proposals here:
http://blog.timbunce.org/2009/10/05/wishlist-of-plperl-enhancements-for-postgresql-8-5/
I'd welcome any feedback on those, and any other suggestions you may have.
(Either here, on the blog, or direct to me - I'll post a summary.)
Thanks.
Tim.
