I'm not suggesting we require perl to be installed to run postgres, or
replace the current regexp implementation with perl. i was just
lamenting the fact that there are no less than 10 different regexp
implementations, with different metacharacters. why should I have to
remember one syntax when I use perl, one for sed, one for emacs, and
another for postgresql? this isn't a problem with postgres per se,
just the fact that there seems to be no standard.
I love perl regex's. I'm merely suggesting (and planning on
implementing) a different set of regexp operators (not included with
postgres, but as a contrib module) that use perl regex's. There are
some pros and cons, which have been discussed.
It should be there for people who want it.
