Обсуждение: pgsql: Update docs as to when WAL logging can be skipped.

Log Message:
-----------
Update docs as to when WAL logging can be skipped.

In 8.4 and prior, WAL-logging could potentially be skipped whenever
archive_mode=off.  With streaming replication, this is now true only
if max_wal_senders=0.

Eh.  I should have written "if it is also the case that max_wal_senders=0".

For the archives, here is the link to the original patch:
