Resolve failures related to pg_node_tree type input

The input function for pg_node_tree pseudotype simply returns an error,
essentially disabling input from text. Some of the regression tests do

    CREATE TABLE t AS SELECT * FROM pg_class;

or something like that, which works fine on PostgreSQL, but it fails on
Postgres-XL as we need to send data between nodes. Unfortunately the
pg_class now contains pg_node_tree column (relpartbound), causing falure
when reading the column on the remote node.

So instead use another catalogue, for example pg_attribute, which does
not contain any such column.
