New scheme for managing platform-specific regress test result files. 

Instead of hard-wiring one result file per platform, there is a map file
'resultmap' that says which one to use --- a lot like template/.similar.
I have only created entries in resultmap for my own platform (HPUX) so
far; feel free to add lines for other platforms.

Introduction
The PostgreSQL regression tests are a comprehensive set of tests for the

operations as well as the extensibility capabilities of PostgreSQL.
These tests have recently been revised by Marc Fournier and Thomas Lockhart
to become current for PostgreSQL v6.1. The tests are now packaged as
functional units and should be easier to run and easier to interpret.
The regression tests were originally developed by Jolly Chen and Andrew Yu,
and were extensively revised/repackaged by Marc Fournier and Thomas Lockhart.
Some properly installed and fully functional PostgreSQL installations
can fail some of these regression tests due to artifacts of floating point

OID differences
There are several places where PostgreSQL OID (object identifiers) appear
in 'regress.out'. OID's are unique 32-bit integers which are generated
by the PostgreSQL backend whenever a table row is inserted or updated.
If you run the regression test on a non-virgin database or run it multiple
times, the OID's reported will have different values.
The following SQL statements in 'misc.out' have shown this behavior:
QUERY: SELECT user_relns() AS user_relns ORDER BY user_relns;

Platform-specific comparison files
Since some of the tests inherently produce platform-specific results,
we have provided a way to supply platform-specific result comparison
files. Frequently, the same variation applies to multiple platforms;
rather than supplying a separate comparison file for every platform,
there is a mapping file that defines which comparison file to use.
So, to eliminate bogus test "failures" for a particular platform,
you must choose or make a variant result file, and then add a line
to the mapping file, which is "resultmap".
Each line in the mapping file is of the form
testname/platformname=comparisonfilename
The test name is just the name of the particular regression test module.
The platform name is the platform name as printed by config.guess (in
the toplevel PostgreSQL src directory), or any prefix of it. The
comparison file name is the name of the substitute result comparison file.
For example: the int2 regress test includes a deliberate entry of a value
that is too large to fit in int2. The specific error message that is
produced is platform-dependent; our reference platform emits
ERROR: pg_atoi: error reading "100000": Numerical result out of range
but a fair number of other Unix platforms emit
ERROR: pg_atoi: error reading "100000": Result too large
Therefore, we provide a variant comparison file, int2-too-large.out,
that includes this spelling of the error message. To silence the
bogus "failure" message on HPPA platforms, resultmap includes
int2/hppa=int2-too-large
which will trigger on any machine for which config.guess's output
begins with 'hppa'. Other lines in resultmap select the variant
comparison file for other platforms where it's appropriate.
