I believe the point is that USES= is the new system and everything is
slowly converting to use it. As I understand it, it is related to
enabling pkg builds to be available with multiple option settings for
each port instead of only default options.

It appears that only one option is available within USES so extra
options need another variable.

As pgsql has USES=pgsql[:version] - WANT_PGSQL is needed for component 
options.

In related news setting the default version in /etc/make.conf is now

DEFAULT_VERSIONS=  pgsql=9.3
