Thread: Regular expressions in procs

I apologize if I'm having a rookie brain block, but is there a way to
massage a string inside a proc to, for instance, strip it of all
non-alpha characters using a regular expression?

regexp_replace() could work for you, see:

SELECT regexp_replace(E'--> text\\\0120815_12 <--', '[^[:alpha:]]', '',
'g');
 regexp_replace
----------------
 text
(1 row)
