+Add a failover option to subscriptions.
+
+This commit introduces a new subscription option named 'failover', which
+provides users with the ability to set the failover property of the
+replication slot on the publisher when creating or altering a
+subscription.
+
+This uses the replication commands introduced by commit 7329240437 to
+enable the failover option for a logical replication slot.
+
+If the failover option is set to true, the associated replication slots
+(i.e. the main slot and the table sync slots) in the upstream database are
+enabled to be synchronized to the standbys. Note that the capability to
+sync the replication slots will be added in subsequent commits.
+
+Thanks to Masahiko Sawada for the design inputs.
