Controls the behavior in response to locking conflicts.

Allowed values

On, Off

Default

On

Scope

Can be set for an individual connection or for the PUBLIC group. Takes effect immediately.

Remarks

If the blocking option is set to On, any transaction attempting to obtain a lock that conflicts with an existing lock held by another transaction waits until every conflicting lock is released or until the blocking_timeout is reached. If the lock is not released within blocking_timeout milliseconds, then an error is returned for the waiting transaction. If the blocking option is set to Off, the transaction that attempts to obtain a conflicting lock receives an error.
