Attached is a patch with some fixes that (I think that) should go into 

6.4.1. Here is the list:

- The type int8 now works. In fact, the bug(s) were in
src/backend/port/snprintf.c, so int8 is probably broken in every platform
that hasn't a native snprintf/vsnprintf. The type itself worked as
expected, only the output was wrong. Anyway, this patch should be checked
in other platforms.

- The regression tests for int2 and int4, which were broken due to
differences in the error messages, are fixed.

- The regression test for float8, which was broken in the reference
platform, is also fixed. I don't know if the new file (float8-OSF1.out)
will work on other platforms, but it might be worth to try it.

- Two new template files are provided (alpha_cc, which includes
optimization, and alpha_gcc), and src/templates/.similar is updated
accordingly. src/templates/alpha should be removed from the distribution.
*IMPORTANT NOTE*: I don't know if you can use gcc to compile postgres;
I've written the alpha_gcc file because alpha_cc has some flags that are
specific to DEC C.

- There is a (very basic) Digital Unix specific FAQ in
doc/FAQ_DigitalUnix.

=======================================================
Frequently Asked Questions (FAQ) for PostgreSQL V6.4.1
FreeBSD Specific
TO BE READ IN CONJUNCTION WITH THE NORMAL FAQ

This FAQ covers issues that are specific for PostgreSQL running on Digital
Unix (formerly known as DEC OSF/1). Please check the global FAQ for questions
not specific to this platform.
Changes in this version (* = modified, + = new, - = removed):
This file is divided approximately as follows:
1.*) Installing PostgreSQL
1.1.*) Compiling PostgreSQL
1.2.*) Running the regression tests
Questions answered:
1.1.1) I can't compile PostgreSQL with gcc.
1.1.2) DEC C dies with an internal error when optimization is
enabled (-O flag).
1.2.1) The regression tests fail for char, varchar, select_implicit,
select_having and rules.
1.2.2) The regression tests fail for abstime, tinterval and horology.
1.2.3) The regression tests fail for geometry.
1.2.4) The regression tests fail for inet.
----------------------------------------------------------------------
Section 1: Installing PostgreSQL
----------------------------------------------------------------------
Section 1.1: Compiling PostgreSQL
------------------------------------
1.1.1) I can't compile PostgreSQL with gcc.
Me too O:-) I tried to compile it with gcc 2.7.2.1 without
success. However, I've found that DEC C works much better than
gcc for alphas, and so I didn't make any effort to find out
why gcc fails. If you succedd on this task, please take the
time to update this section (see http://www.postgresql.org for
the details on how to do this).
1.1.2) The DEC C compiler dies with an internal error when optimization is
enabled (-O flag).
I've seen this happening on 3.2c and 3.2g systems, and only on
one of the source files (can't remember exactly which one).
The workaround was to compile the offending module without
optimization by hand, and re-running gmake to let the process
continue.
It doesn't happen on 4.0d systems (mine at least). Don't know
about earlier 4.0 versions.
Section 1.2: Running the regression tests
--------------------------------------------
1.2.1) The regression tests fail for char, varchar, select_implicit,
select_having and rules.
This only happens when you enable locale support, and is due
to a bug in the system's locale libraries. The problem is
that strcoll("Axxx", "axxx") returns a value greater than
zero instead of lower, which is how it should be.
This isn't a great problem unless you (or your application)
relies on upper-case letters being considered "smaller" than
lower-case for ordering purposes. Otherwise, you will only
notice that the ordering between upper-case and lower-case
letters is reversed.
1.2.2) The regression tests fail for abstime, tinterval and horology.
I think that these failures are due to some inconsistencies
in time zone handling in some years near 1950, in which case
the problem would be in the operating system's time zone
libraries. Recent dates seem to work as expected, but I can't
assure it.
1.2.3) The regression tests fail for geometry.
These are (small) rounding errors that shouldn't affect any
application (but could do, who knows).
1.2.4) The regression tests fail for inet.
Yes, they do. You must consider the inet type broken for
Digital Unix.
