-- Both tables are created by every replica at startup, so every statement is IF NOT EXISTS.
-- The shedlock table's shape is fixed by ShedLock: name, lock_until, locked_at, locked_by.
-- lock_until and locked_at must be timestamps; with usingDbTime() they are written by the
-- database, so their precision and time zone are the database's, not the JVM's.
