Tom Lane 99772d6465 Fix estimate_num_groups() to assume that GROUP BY expressions yielding boolean ... results always contribute two groups, regardless of the expression contents. This is very substantially more accurate than the regular heuristic for certain boolean tests like "col IS NULL". Per gripe from Sam Mason. Back-patch to all supported releases, since the behavior of estimate_num_groups() hasn't changed all that much since 7.4.		2008-07-07 20:25:40 +00:00
