Thread: max_stack_depth error, need suggestion

I am using Postgresql 9.0.1 in Centos 5.

Yesterday, I got the error inlog:

2011-08-16 10:57:34 EDT [3868]: [1-1] user=vcrm,db=vtigercrm504 ERROR:  stack depth limit exceeded
2011-08-16 10:57:34 EDT [3868]: [2-1] user=vcrm,db=vtigercrm504 HINT:  Increase the configuration parameter "max_stack_depth", after ensuring the platform's stack depth limit is adequate.


I found that I need to increase max_stack_depth. But doc says that it is a bit risky increasing it.

Could any one please suggest me what the maximum safe value I may set in my environment?

My Server RAM is 32 GB.

That error message is usually caused by an infinite recursion.

Slony can also cause this to happen (at least it could - I'm not sure if it still does) - it wasn't from infinite
recursionthough.  I used to have to set that higher for some of my clusters.  They may have fixed the query that was
causingthat to happen though.
