Please enter a FULL description of your problem:
------------------------------------------------

In 64 bit machines like the Ultraparc, strncmp can return -256.
In src/backend/utils/adt/name.c you do:
                return (bool) strncmp(arg1->data, arg2->data, NAMEDATALEN)
== 0;
In this way you are casting strncmp to bool, and not the comparison.

This is the description of the consequences, that I sent before I
discovered the problem:
(I am giving a really detailed description to maximize the chances that
you find the solution to my problem)

I have installed postgres many times in several Linux/Intel systems.

Now, I am trying to install Pg 6.5.3 ( or any other version of Pg) in a
Linux/(ultra)Sparc system. The system seems stable in any task other than
postgres stuff, but when I run initdb, it always dies with and error
about :
"Attribute 'aggtransfn1' is repeated."

I have downloaded source distribution PG 6.5.3, PG Snapshot, PG 6.5.2
and RPM binaries of Pg from RedHat 6.1 distribution and even SRPMS.

In all of them, after compiling and/or installing, when I do the initdb
-d, the script dies with this message:

> <aggname name>
<aggowner int4>
<aggtransfn1 regproc>
<aggtransfn2 regproc>
<aggfinalfn regproc>
<aggbasetype oid>
<aggtranstype1 oid>
<aggtranstype2 oid>
<aggfinaltype oid>
<agginitval1 text>
<agginitval2 text>
> ERROR:  Attribute 'aggtransfn1' is repeated
ERROR:  Attribute 'aggtransfn1' is repeated
initdb: could not create template database
initdb: cleaning up by wiping out /usr/local/pgsql/data/base/template1

I have also tried initdb with the full command line, etc..

This happens with all the versions of Pg that I have tested:
   Pg Snapshot 22 Nov
Pg 6.5.3,
Pg 6.5.2,
Binaries in RPM from RedHat 6.1 Sparc
Source SRPM from '' ''


Then, I investigated the problem deeper, and deeper.
If I remove aggtransfn2 from the local1.????.bki.source, it gives the same
error in agginitval2.

I replaced the ERROR with a NOTICE on the elog on the file
src/backend/catalog/heap.c in the function CheckAttributeNames() and
everything went ok until I started regression tests. Lots of 'failed'
appeared in the char/string related tests, and those were real problems,
because I checked it myself (not just little differences); the backend
closed connection in some tests.

 I then added some lines in the src/backend/catalog/heap.c to see if the
strings were read ok and if NAMEDATALEN was ok. Yes, they were.
aggtransfn1 was compared to aggransfn2 by a call to nameeq(), and this
function returned that they were equal (obviously they differ on the last
character).

Then, finally I replaced the call to nameeq to a direct strncmp() between
both tuple->data's and it worked. The regression tests still failed.

Maybe there is a problem in the strncmp libraries in my system ? oh no...

[PS: The source of this problem as I wrote above, is in Postgres name.c
file, in nameeq() ]

Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------

configure --with-x --with-tcl --with-template=linux_sparc
make
make install
cd /usr/local/pgsql
initdb




If you know how this problem might be fixed, list the solution below:

I send both diff -f and diff -u in attach
