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.
I have gathered statistics with count of WAL files created on specific dates as shown below:
Date | WAL file count
-----------| -------------
2016-08-31 | 1569
2016-08-30 | 3031
2016-08-29 | 2664

2016-08-27 | 1231
2016-08-26 | 1946
2016-08-25 | 1850

here we are expecting normal count to be between 600 to 800 according to our database transactions. But in above statistics you can see major fluctuation in file counts. I do not understand where the problem is and how can I find the
root cause of the problem ?
Also I would like to inform that few days back I had performed full vacuum on 2 or 3 tables which were having size of 3 to 4 GB. But I do not guess it is because of this vacuum.
So could you please provide me guidelines to get this problem solved ?
