Modified files:
	src/backend/optimizer/path: costsize.c joinpath.c 

Log message:
	Support FULL JOIN with no join clauses, such as X FULL JOIN Y ON TRUE.
	That particular corner case is not exactly compelling, but given 7.4's
	ability to discard redundant join clauses, it is possible for the situation
	to arise from queries that are not so obviously silly.  Per bug report
	of 6-Apr-04.
