Tom Lane 757dfd6327 Tweak joinlist creation to avoid generating useless one-element subproblems ... when collapsing of JOIN trees is stopped by join_collapse_limit. For instance a list of 11 LEFT JOINs with limit 8 now produces something like ((1 2 3 4 5 6 7 8) 9 10 11 12) instead of (((1 2 3 4 5 6 7 8) (9)) 10 11 12) The latter structure is really only required for a FULL JOIN. Noted while studying an example from Shane Ambler.		2007-01-08 16:47:35 +00:00
