BTW, I wonder whether it wouldn't be a better idea to declare the
pg_prepared_statement view's parameter_types column as regtype[]
instead of oid[].  This would make the default output much more
readable, ie you'd get things like '{integer,boolean}' instead of
'{23,16}'.  Of course you can cast in either direction to get the
other form, but defaulting to text instead of numeric output seems
like it might be a better choice.

The option of casting to get the other form should probably be mentioned
in the view's documentation page, whichever is the default.
