BuildWorkerScan builds a callback that can be used as a `Scan` field in an `Options` struct.

ErrDequeueRace occurs when a record selected for dequeue has been locked by another worker.

ErrDequeueTransaction occurs when Dequeue is called from inside a transaction.

ErrExecutionLogEntryNotUpdated is returned by AddExecutionLogEntry and UpdateExecutionLogEntry, when the log entry was not updated.

ErrNoRecord occurs when a record cannot be selected after it has been locked.

Options configure the behavior of Store over a particular set of tables, columns, and expressions.

Store is the persistence layer for the dbworker package that handles worker-side operations backed by a Postgres database.
