The server is in localhost. 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.
