In my Postgresql (9.2 version) generates write ahead log (WAL) of 16MB for everysecond i.e. 60 WALs are generated in One Minute., though no transactions are executing in the database
Can it possible to make them occur less frequency.
Can it possible to increase the WAL file size, so that less WALs will generate in One minute

any insights are welcomed..

Thanks in advance
