That will be a very useful feature. I don' t care if i loss 1-2 hours of data. I know we could have some cron jobs to dump the table periodically but the table could be big, so this operation could be expensive. Also i have to detect when postgres crush, i have no idea how i can detect if postgres crushed. Then i have somehow to attache a script at postgres start, to restore the dumps...the dump solution is very complicate and unreliable. A periodic flush feature will be amazing! How is the procedure for feature request on postgres, github?
