unless madhavi is running postgres in windoze.
cron is a reliable way of executing psotgresql tasks.
Some Tips:
1. I find it helpful to put the SQL related crons under
a dedicated user , so that i dont have to hunt around
to get the list of all scheduled SQLs.
2. If sql batch is to be run its better to use a .sql script
with all the SQL statements in it and enclosed in
a BEGIN WORK ; <SQLS> ; COMMIT;
3. MAILTO env variable shud be set to get error reports
on SQL activity.
4. -q or -e option can be with psql depending on need.
