* Do not set pending_restart flag if hot_standby is set to 'off' during a custom bootstrap (even though we will have this flag actually set in PG, this configuration parameter is irrelevant on primary and there is no actual need for restart)
* Skip hot_standby and wal_log_hints when querying parameters pending restart on config reload. They actually can be changed manually (e.g. via ALTER SYSTEM) and it will cause the pending_restart state in PG but Patroni anyway always passes those params to postmaster as command line options. And there they only can have one value - 'on' (except on primary when performing custom bootstrap)
