Fujii Masao 93eb619cd3 Ensure that num_sync is greater than zero in synchronous_standby_names. ... Previously num_sync could be set to zero and this setting caused an assertion failure. This means that multiple synchronous standbys code should assume that num_sync is greater than zero. Also setting num_sync to zero is nonsense because it's basically the configuration for synchronous replication. If users want not to make transaction commits wait for any standbys, synchronous_standby_names should be emptied to disable synchronous replication instead of setting num_sync to zero. This patch forbids users from setting num_sync to zero in synchronous_standby_names. If zero is specified, an error will happen during processing the parameter settings. Back-patch to 9.6 where multiple synchronous standbys feature was added. Patch by me. Reviewed by Tom Lane.
