Integer, in milliseconds.
0
Option can be set at the database (PUBLIC) or user level. When set at the database level, the value becomes the default for any new user, but has no impact on existing users. When set at the user level, overrides the PUBLIC value for that user only. No system privilege is required to set option for self. System privilege is required to set at database level or at user level for any user other than self.
Requires the SET ANY PUBLIC OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect immediately.
When the blocking option is on, any transaction attempting to obtain a lock that conflicts with an existing lock waits for the indicated number of milliseconds for the conflicting lock to be released. If the lock is not released within blocking_timeout milliseconds, an error is returned for the waiting transaction.
Set the option to 0 to force all transactions attempting to obtain a lock to wait until all conflicting transactions release their locks.
