autodoc - autodoc: New versions of DBD::Pg like to return an array

Log Message:
-----------
New versions of DBD::Pg like to return an array reference instead of the special text string that PostgreSQL returns.

This might take care of the issue, although only partially tested (FreeBSD ports doesn't have the newer version yet as it breaks a number of applications).
