Re: patch adding new regexp functions

That only works with fixed delimiters, and I was hoping that
regexp_split would be an alternative with regexp delimiters.  It's
certainly another argument that all the split functions in PostgreSQL
should offer analogous interfaces.  There is no reason being offered
why splitting on a fixed string should result in an array and splitting
on a regexp should result in a table.

We already have tsearch for that.
