regexp_replace - Mailing list pgsql-general

Hi all.

This is not doing as I'd expected:

select regexp_replace('71.09.6.01.3', '(\d)[.-](\d)', '\1\2', 'g');

  regexp_replace
----------------
  71096.013
(1 row)

It acts the same with dashes:
select regexp_replace('71-09-6-01-3', '(\d)[.-](\d)', '\1\2', 'g');

  regexp_replace
----------------
  71096-013
(1 row)

I cannot use translate because there is other text in the field.  I'm
trying to strip masking characters from a parcel number in a larger text
field (for example:  "the parcel 12-34-56 has caught on fire")

I seem to be missing something, any hints?

I'm on PG 9.3.9 on Slackware64.

Thanks for your time,

-Andy
