I am not opposed to moving the contrib code into core in the manner that you oppose. I don't feel strongly either way.
I noticed in passing that your revision says this *within* levenshtein.c: + * Guaranteed to work with Name datatype's cstrings. + * For full details see levenshtein.c.

I lean slightly towards "no", as already explained  , but it's not as if I feel that strongly either way - this approach of looking for only a single best candidate per RTE taken in deference to the concerns of others. I imagined that when a committer picked this up, an executive decision would be made one way or the other. I am quite willing to revise the patch to alter this behavior at the request of a committer.  http://www.postgresql.org/message-id/CAM3SWZTrm4PmqMmL9=eyx-8f-vx-ha7dme4koms2vcomozg...@mail.gmail.com  http://www.postgresql.org/message-id/cam3swzs6kiqeqjz4pv3fkp6cgw1ws26exoqtjb_xmw3ze5b...@mail.gmail.com -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
