[Pkg-postgresql-public] Bug#760564: postgresql-9.4: regexp_matches behavior change 9.3 -> 9.4

[Jérémy Lal]

Package: postgresql-9.4
Version: 9.4~beta2-1+b1
Severity: normal

Dear Maintainer,

With postgres 9.3 i have
select regexp_matches('gestion/football/ligue-des-champions', '^((?!d{4}-d{1,2}-d{1,2})[^/]+?)(?:/((?!d{4}-d{1,2}-d{1,2})[^/]+?))(?:/((?!d{4}-d{1,2}-d{1,2})[^/]+?))?$', 'g');
             regexp_matches             
----------------------------------------
 {gestion,football,ligue-des-champions}

With postgres 9.4 it returns 0 row. Removing the greedy quantifier at the end
[^/]+? -> [^/]+
makes it return a result again.

Regards,
Jérémy.
