Subject: Reduce WAL archive length.
X-Git-Url: https://git.openstreetmap.org./chef.git/commitdiff_plain/86aa04a67f5f1c0f0e556ecb969287a1573831ba?ds=sidebyside;hp=86aa04a67f5f1c0f0e556ecb969287a1573831ba

Reduce WAL archive length.

Was 40 days, this reduces it to 21 days. That should roughly halve
the amount of disk space needed to store all the WALs, at the cost
that it's more difficult to recover a replica which has been out of
sync for between 22 and 40 days.

Closes #121
