Previously, the check_hook for synchronized_standby_slots attempted to validate that each specified slot existed and was physical. However, these checks were not performed during server startup. As a result, if users configured non-existent slots before startup, the misconfiguration would go undetected initially. This could later cause parallel query failures, as newly launched workers would detect the issue and raise an ERROR. This patch improves the check_hook by validating the syntax and format of slot names. Validation of slot existence and type is deferred to the WAL sender process, aligning with the behavior of the check_hook for primary_slot_name.
