Hi all,

It must be that I haven't had enough caffeine today, but I can't figure out why the following expression captures the non-capturing part of the text:

# SELECT regexp_matches('postgres','(?:g)r');
 regexp_matches 
----------------
 {gr}
(1 row)

I'm expecting '{r}' in the output as I thought this would use ARE mode by default.

Thom
