Haven't there been some over enthusiastic cleanup scripts in some Linux distro's, that removed the socket
from /tmp because of it's age?
Anyway, so in summary:
1. The test case was the *well known* MySQL favorite suite; Simple one-table read-only access with
myriads of connect's.
2. The *well known* fact that PostgreSQL out of the box is not configured for production was ignored.
3. Any possibility to track down the reasons for problems was disabled.
4. Instead of investigating what the problem is, PostgreSQL was reported to *Crash*.
It cannot get any more obvious.
