Fix and clarify information schema interval_precision fields

Browse Source 
The fields were previously wrongly typed as character_data; change to
cardinal_number.  Update the documentation and the implementation to
show more clearly that this applies to a feature not available in
PostgreSQL, rather than just not yet being implemented in the
information schema.
