bgwriter_lru_maxpages range in postgresql.conf

(My earlier post has been stuck in infinite moderation due to the use of a
common 6 letter abbreviation for configuration, so I will try again without
it)

With v10, commit 14ca9abfbe4643408a, the upper limit on
bgwriter_lru_maxpages was changed from 1000 to INT_MAX / 2, but
the postgresql.conf.sample was not updated.

#bgwriter_lru_maxpages = 100 # 0-1000 max buffers written/round

I don't see any precedence for including INT_MAX-type limits in the sample
configuration file, so maybe something like this:?

#bgwriter_lru_maxpages = 100 # max buffers written/round, 0 to turn
off

Cheers,

Jeff
