I am now testing REL_13_STABLE (ba9f665a4413f855bbf4b544481db326f7b9bd73) vs
master (c1132aae336c41cf9d316222e525d8d593c2b5d2). The regular expressions we
discussed upthread show no differences.
There are a few changes which appear correct to me, but I don't know if you
expected them:
select regexp_match('hko', '((((?<!.))))(.(\3)(\1.))');
- regexp_match
---------------
-
+ regexp_match
+--------------------
+ {"","","",hk,"",k}
(1 row)
select 'nigqvigqvee' !~ '(())((\2)\2)(?:([^\W]))';
-ERROR: invalid regular expression: invalid escape \ sequence
+ ?column?
+----------
+ f
+(1 row)
+
select regexp_replace('tl', '.{0}?(((?<![^][^]{1}?)))(.)\2{6}?', 'jx', 'mt');
regexp_replace
----------------
- tl
+ jxl
(1 row)
