Обсуждение: metaphone and nysiis in postgres
Microsoft SQL server has two extended stored procedures that I need in Postgres: xp_nysiis and xp_metaphone. They do fuzzymatching on strings. Are there Postgres alternatives for these? Or maybe some other way to do phonetic/fuzzy matchingthat would be as effective? -Jeff -----Original Message----- From: pgsql-sql-owner@postgresql.org [mailto:pgsql-sql-owner@postgresql.org] On Behalf Of A.

Never heard of nysiis, but there's metaphone code in contrib/fuzzystrmatch
(along with a few other alternatives).

Ah! Cool. Contrib/fuzzystrmatch has metaphone. Looks like it has
soundex and levenschtein too.
Thanks!

I don't have a problem with doing this in our development environment, but when we go to move it onto the live production box, with all the live data and current custom settings, will a re-install cause issues? Data loss is unacceptable, of course, but it would also be nice if we don't have to juggle users, permissions, and settings. -Jeff -----Original Message----- From: Richard Huxton [mailto:dev@archonet.com] Sent: Thursday, February 08, 2007 3:06 AM To: Demel, Jeff Cc: pgsql-sql@postgresql.org Subject: Re: [SQL] metaphone and nysiis in postgres Demel, Jeff wrote: > Can this be installed easily on Windows?
