Tom Lane bfd1ffa948 Change patternsel (LIKE/regex selectivity estimation) so that if there ... is a large enough histogram, it will use the number of matches in the histogram to derive a selectivity estimate, rather than the admittedly pretty bogus heuristics involving examining the pattern contents. I set 'large enough' at 100, but perhaps we should change that later. Also apply the same technique in contrib/ltree's <@ and @> estimator. Per discussion with Stefan Kaltenbrunner and Matteo Beccati.		2006-09-20 19:50:21 +00:00
