Description of problem:
I have just downloaded Red Hat Database 2 and loaded it on Red Hat Linux 7.3 (1.2 GHz Duron
processor using the Athlon kernel, with system updates to 2002-10-10) and run the regression test.
The following was in the "regression.diff" file:

*** /usr/lib/pgsql/test/regress/expected/random.out	Thu Jan  6 06:40:54 2000
--- /usr/lib/pgsql/test/regress/results/random.out	Sun Dec  8 21:19:56 2002
*** 31,35 ****
    WHERE random NOT BETWEEN 80 AND 120;
! (0 rows)
--- 31,36 ----
    WHERE random NOT BETWEEN 80 AND 120;
!     122
! (1 row)

First, thanks for downloading RHDB 2.0. 

The community random test will fail sometimes.  Rerunning the regression
test will probably give a different result. It's in the PostgreSQL community
archives as well as the RHDB documentation at the bottom of this page:


The RHDB 2.0 documentation does not contain information on how to rebuild from
source so the above link is not present in the RHDB 2.0 Getting Started / 
Installation Guide.  

I'm returning this bug with the above explanation.  Please respond or close
this bug at your earliest convenience.  If I don't we don't hear back from
you by end of week, I'll assume that it's ok to close this bug.

     I have been reading the documentation for RHDB 2.0 for the last few days
in order to understand the situation better.  Unfortunately, there is a *lot*
I still have to read.  I have read the online page you pointed out.

     It is still not clear whether this is just "a known issue (ie. not
really a bug at all) in the test program," or whether something is actually
wrong.  I have not had a chance to use that computer to re-run the test yet.

     Due to the above, I have no opinion whether the bug should be "closed."
Perhaps you can leave it open in case someone else has the time to address

Comment 3 Patrick Macdonald 2002-12-16 15:47:59 UTC
This is a known issue with the PostgreSQL community regression test
bucket.  Once every X times, the random test will fail.  It's not
really a bug, but it is a poorly designed test.  The RHDB post-installer
regression test bucket combines the entire PostgreSQL community
test with several RHDB specific ones.   

The RHDB post-installer checks to see if you failed on that specific
test.  If it finds a failure, the failure is reported but there should
also be some output stating that this failure can be safely ignored.

I'm going to close this as NOTABUG and will note the Random test failure
on the FAQ at sources.redhat.com/rhdb.
