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. -- ------------------------------------------------------------------- Pedro José Lobo Perea Tel: +34 91 336 78 19

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.

|
|
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.
