Re: Estimating WAL usage during pg_basebackup

This is hard to tell, but You can get some estimation.
1. You can have WAL rate estimation from pg_xlog/ dir, i.e. How many WAL
generated per minutes
2. How long this pg_basebackup will last. Lets say for 3 hours.
Then You can multiple values in #1 and #2 to get rough estimation.

Hope this would help.
