Onder Kalaci 6532b69873 Kill the maintenance daemon on DROP DATABASE 2017-08-18 16:03:08 +03:00
Onder Kalaci e5d5bdff51 Enable distributed deadlock detection on the maintenance deamon 
With this commit, the maintenance deamon starts to check for
distributed deadlocks.

We also introduced a GUC variable (distributed_deadlock_detection_factor)
whose value is multiplied with Postgres' deadlock_timeout. Setting
it to -1 disables the distributed deadlock detection.

Andres Freund c3b7c5dc33 Introduce per-database maintenance process. 
This will be used for deadlock detection, prepared transaction
recovery amongst others, but currently is just idling around.
