In my environment, if I run the query in psql, everything is good.  However if 

I run it in some java code(including other sql),  it would crash for 95% cases. 

I'm sorry that I can't provide a runnable test case,  I'm posting here just to see

if anyone has run into the similar case before or can provide some hints on this.

Thanks!
