about whether it is applied before or after eval_const_expressions().
I believe there were some corner cases where the system would fail to
recognize that a partial index is applicable because of the previous
inconsistency. Store normal rather than 'implicit AND' representations
of constraints and index predicates in the catalogs.
initdb forced due to representation change of constraints/predicates.

Here is an updated patch that does that.

This seems cleaner, and also opens the door to making the choice be
dependent on the compiler being used.

use HAVE_SPINLOCKS in preference to HAS_TEST_AND_SET everywhere outside
s_lock.h itself.

The patch basically is a slight rearrangement of the code to allow
fork/exec on Unix, with the ultimate goal of doing CreateProcess on
Win32. The changes are:
o Write out postmaster global variables and per-backend
variables to be read by the exec'ed backend
o Mark some static variables as global when exec is used so
then can be dumped from postmaster.c, marked NON_EXEC_STATIC
o Remove value passing with -p now that we have per-backend
file
o Move some pointer storage out of shared memory for easier
dumping.
o Modified pgsql_temp directory cleanup to handle per-database
directories and the backend exec directory under datadir.

to step more than one entry after descending the search tree to arrive at
the correct place to start the scan. This can improve the behavior
substantially when there are many entries equal to the chosen boundary
value. Per suggestion from Dmitry Tkach, 14-Jul-03.
a) ones that are 100% backward (such as the comment about
outputting this format)
and
b) ones that aren't (such as deprecating the current
postgresql shorthand of
'1Y1M'::interval = 1 year 1 minute
in favor of the ISO-8601
'P1Y1M'::interval = 1 year 1 month.
Attached is a patch that addressed all the discussed issues that
did not break backward compatability, including the ability to
output ISO-8601 compliant intervals by setting datestyle to
iso8601basic.
Interval values can now be written as ISO 8601 time intervals, using
the "Format with time-unit designators". This format always starts with
the character 'P', followed by a string of values followed
by single character time-unit designators. A 'T' separates the date and
time parts of the interval.

to completion. This fixes the problem for SQL-language functions, but
still need work on functions using the SRF_XXX() macros.

when in Informix mode.

Shouldn't this be HeapTupleHeaderData and not HeapTupleData ?
(Of course, from a costing perspective these shouldn't be very different but ...)
