I have mentioned this in my previous mail but may be it has some problem
http://archives.postgresql.org/pgsql-hackers/2012-12/msg00062.php
The current behavior is
1. "RESET PERSISTENT ..." will delete the entry from postgresql.auto.conf
2. "SET PERSISTENT... TO DEFAULT" will update the entry value in
postgresql.auto.conf to default value
However we can even change "SET PERSISTENT... TO DEFAULT" to delete the
entry and then we can avoid "RESET PERSISTENT ..."
Opinions?
