Dear Matthew, Scot,

There are no ways to control default value of failover. Regarding the way for
changing the value, yes, ALTER_REPLICATION_SLOT replication command is an only
way to do that. Note that it's acceptable only when the backend is in the
replication mode - normal backend cannot understand them.

Best regards,
