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 ?
