Function: withAdvisoryLock()
withAdvisoryLock<
T>(__namedParameters):Promise<T>
Defined in: advisoryLock.ts:30
Runs fn while holding a Postgres session-level advisory lock
(pg_advisory_lock), acquired and released on a single dedicated connection.
A naive sequelize.query() lock/unlock pair can land on different pooled
backends and try to unlock a lock the current connection never held, so the
connection is borrowed once and kept for the whole critical section. The
lock is always released on both the success and failure paths.
