Non-capturing expressions

[Thom Brown <thom@xxxxxxxxx>]

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.
