pgsql: oid2name: Add relation path to the information provided by -x/--

oid2name: Add relation path to the information provided by -x/--extended

This affects two command patterns, showing information about relations:
* oid2name -x -d DBNAME, applying to all relations on a database.
* oid2name -x -d DBNAME -t TABNAME [-t ..], applying to a subset of
defined relations on a database.

The relative path of a relation is added to the information provided,
using pg_relation_filepath().
