> PostgreSQL version: 9.4.8

> Description:
>
> I have setup PITR in PostgreSql. I am taking base backup at every specific
> interval and also kept WAL files of size 16 MB each.

> Now the situation is that even there is no any major change in database, it
> suddenly started creating too many WAL files.

> Date | WAL file count
