That's not quite accurate - there are three cookies set by *.postgresql.org:

postgresql.org - csrftoken (expires a year after being set)
postgresql.org - sessionid (expires two weeks after being set)
wiki.postgresql.org - wikidb_session (expires on browser close)

Only the sessionid cookie requires a https connection, the other cookies 
will be sent if a request is made over a http connection.

If all wiki connections should be over https - including guests - then 
that can be accomplished via a simple rule in the Apache virtual host 
configuration. If only logged in users require https then you'd need 
either a plugin to handle this, or register a 'hook' which is a small 
piece of PHP which is run before Mediawiki displays a page and forces a 
redirect if the request was not made over https *and* the wikidb_session 
cookie is set.
