const TXLOCKING = "immediate"

TXLOCKING - transaction locking. Can be 'auto', 'immediate' or 'exclusive'. 'immediate' means no other writes to db once the transaction is in progress. When we create our db with 'immediate' flag, all transactions will be in 'immediate' mode. Basically, that buys us locking across the query+upate operations if they are part of the same transaction. On the postgress side, the equivalent is the "QUERY FOR UPDATE" clause.
