Bug reference: 15046

PostgreSQL version: 10.1
Operating system: windows 10
Description:
I start psql; enter:
postgres=# select regexp_replace('a(d)s(e)f', '\(.*?\)', '', 'g');
regexp_replace
----------------
asf
(1 row)
Works as expected. Then I add |q to the pattern, and the .*? becomes
greedy!
postgres=# select regexp_replace('a(d)s(e)f', '\(.*?\)|q', '', 'g');
regexp_replace
----------------
af
(1 row)
