pgsql: Rename the parameter recovery_connections to hot_standby, to - Mailing list pgsql-committers

Log Message:
-----------
Rename the parameter recovery_connections to hot_standby, to reduce possible
confusion with streaming-replication settings.  Also, change its default
value to "off", because of concern about executing new and poorly-tested
code during ordinary non-replicating operation.  Per discussion.

In passing do some minor editing of related documentation.
