Doc: update remaining tables of functions/operators for new layout. 

This converts the contrib documentation to the new style, and mops up
a couple of function tables that were outside chapter 9 in the main
docs.

A few contrib modules choose not to present their functions in the
standard tabular format.  There might be room to rethink those decisions
now that the standard format is more friendly to verbose descriptions.
But I have not undertaken to do that here; I just converted existing
tables.

These operators do not make a lot of sense for any practical
purpose but sorting. These operators first compare (a) to (c),
and if these are equal, compare (b) to (d). That results in and if these are equal, compare (b) to (d). That results in
reasonably good sorting in most cases, which is useful if reasonably good sorting in most cases, which is useful if
you want to use ORDER BY with this type. you want to use ORDER BY with this type.
