Tom Lane b4df57ff9f Improve match_special_index_operator() to recognize that LIKE with an ... exact-match pattern (no wildcard) can be index-optimized in some cases where a prefix-match pattern cannot; specifically, since the required index clause is simple equality, it works for regular text/varchar indexes even when the locale is not C. I'm not sure how often this case really comes up, but since it requires hardly any additional work to handle it, we might as well get it right. Motivated by a discussion on the JDBC list.		2009-03-11 03:32:22 +00:00
