You should get on the screen (and also written to file ./regress.out)

Now do some intelligent interpretation of what you see before
deciding if you have detected a bug in PostgreSQL as it compiled on
you platform.
For example. On a SPARC/Linux-elf platform using the 970516 beta
version of PostgreSQL v6.1 the following tests "failed". float8
and geometry "failed" due to minor precision differences in floating
point numbers. timespan and horology had different values from the
expected "14 secs ago". (This may be a real bug. It may simply be
problems with convincing the back end what timezone and time to
use.) datetime, abstime and tinterval failed because it used GMT
where it should have used PST and PDT. (Same comment.) select_views
failed for unknown reasons. Conclusion? There may be some real
bugs exhibited here but will they effect what you intend to use
PostgreSQL for? (Note: Most of these bugs also occur on the
i86/Linux platform. Also note that there will be significant
changes made to the date and time types immediately after the
v6.1 release so if you do need these functions, monitor the HACKERS
and PORTS mailing lists to see what is going on.)
"Failed" tests may have failed due to slightly different error messages,
output formatting, failure to set the timezone correctly for your
platform, etc. "Failures" of this type do not indicate a problem with
PostgreSQL.
Here is an example from a i686/Linux-ELF platform (this is the platform
on which most of the regression tests were generated). float8 failed
on exponentiation and logarithmic operations due to known differences
in error handling for those math functions between this platform
and the original Sun (?) Postgres v4.2 development environment.
Here is an example from a SPARC/Linux-ELF platform (note that this is
for an "unsupported" platform). Using the 970516 beta version of
PostgreSQL v6.1 the following tests "failed". float8 and geometry
"failed" due to minor precision differences in floating point numbers.
timespan and horology had different values from the expected
"14 secs ago". datetime, abstime and tinterval had "GMT" for the time
zone rather than "PST" or "PDT". These differences were due to a
mis-typed string for the TZ environment variable from step (18).
select_views failed for unknown reasons.
Conclusion? If you do see failures, try to understand the nature of
the differences and then decide if those differences will affect your
intended use of PostgreSQL. However, keep in mind that this is likely
to be the most solid release of PostgreSQL to date, incorporating many
bug fixes from v6.0, and that previous versions of PostgreSQL has been
in use successfully for some time now.

Linux:
The linux port defaults to the ELF binary format. (Note that if you're
using ELF, you don't need dld because you'll be using the dl library
that comes with Linux ELF instead.)
The linux-elf port installs cleanly. If you are using an
i486 processor or higher, you can edit template/linux-elf
to include "-m486" as a compiler option. configure does not
detect that sigsetjmp() is available, but you can edit
include/config.h after running configure and before running
make to include "#define HAVE_SIGSETJMP 1". Note that I have
not seen any difference in PostgreSQL behavior either way.
