Fix documentation for max_wal_size and min_wal_size

[sirisha chamarthi]

Hi,

The documentation [1] says max_wal_size and min_wal_size defaults are 1GB
and 80 MB respectively. However, these are configured based on the
wal_segment_size and documentation is not clear about it. Attached a patch
to fix the documentation.

Thanks,
Sirisha
