Implement remaining fields of information_schema.sequences view

Browse Source 
Add new function pg_sequence_parameters that returns a sequence's start,
minimum, maximum, increment, and cycle values, and use that in the view.
(bug #5662; design suggestion by Tom Lane)

Also slightly adjust the view's column order and permissions after review of
SQL standard.
