I don't use pl/perl, but I've seen a very similar "could not load library" error with pl/python on Windows, even though the dll named was present. Windows gives very bad error messages when it fails to dynamically link. You could use something like dependency walker, which is probably a pain. I think that plperl.dll simply wants to link to a major version of perl that you don't have. It's a matter of finding out which and installing it. -- Regards, Peter Geoghegan -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
