[GitHub] [spark] cloud-fan commented on pull request #29891: [SPARK-30796][SQL] Add parameter position for REGEXP_REPLACE

   We need more information to decide the behavior:
   1. does other DBs support non-literal position parameter?
   2. does other DBs support negative position value? Seems Redshift supports it
   3. does other DBs support position parameter in all regex like functions?
