Dear Jochen,

Thank you for suggesting the valuable URL, we are getting 3 "floating point assist fault" error for every second, will it impact the performance for postgresql?

Is there any option to turn on "flush to zero mode" in itanium cpu while compiling postgresql from source?

Thank you for your valuable time to read this.

Regards,

Muthu

A quick search for 'floating-point assist fault' reveals this article:

In short: The message is harmless, and should not have any influence on
postgres performance, except if you're getting millions of them...
