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?

Perhaps. You can, for instance, with extract(epoch from stop_date_time) retrieve the number of seconds and work with
this.
