Default deadlock_timeout parameter in Postgresql.cof

I am having some dead locking problem with my app system. Our dev are
debugging the app to find out the cause of the problem. In the mean time
I looked at postgresql.conf file. I found that there is a parameter in
postgresql.conf file deadlock_timeout which was set 1000 (ms). Normally
I see deadlock in the night or when auto vacuum is running for a long
time.



My question is



What is the significance of this parameter and updating this parameter
value will make any difference ?



Thanks

Regards

sachi

Does the documentation leave anything unanswered?
