npgsql - Npgsql2: Fixed problem when calling functions with inout or

Log Message:
-----------

Fixed problem when calling functions with inout or out parameters. They
were being incorrectly added with a column list which was complained by
postgresql server: ERROR: 42601: a column definition list is only
allowed for functions returning "record". See
http://pgfoundry.org/forum/forum.php?thread_id=1075&forum_id=519 for
discussion about this. Thanks very much to Anton Andreev (fn30762
at fmi dot uni-sofia dot bg) for his help providing test cases.
