  1. Add vacuum_truncate configuration parameter. 

    This new parameter works just like the eponymous storage parameter:
if set to true (which is the default), autovacuum and VACUUM
attempt to truncate any empty pages at the end of the table.  It is
primarily intended to help users avoid locking issues on hot
standbys.  The setting can be overridden with the storage parameter
or VACUUM's TRUNCATE option.

Since there's presently no way to determine whether a Boolean
storage parameter is explicitly set or has just picked up the
default value, this commit also introduces an isset_offset member
to relopt_parse_elt.
