https://wiki.shibboleth.net/confluence/display/IDP30/RelationalDatabaseConnector and look for validatorRef in the Attribute section

Absolutely not, many people configure a static connector for failover.  Note that failover is what happens if there is a failure
during resolution, not during initialization.
