The binaries are from enterpriseDB. I also downloaded src code for Postgres 9.1.11. Recompiled fuzzystrmatch, which includes levenstein less_equal. Replaced .so file in Postgres installation dir. Change in levenshtein limit of character successful. It is not a compilation error, because I do not get levenstein less_equal in the Postgres 9.2 server which is exactly as downloaded from EnterpriseDB. -- View this message in context: http://postgresql.1045698.n5.nabble.com/levenshtein-less-equal-does-not-work-tp5788710p5788723.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
