any amount of leading or trailing whitespace (where "whitespace"
is defined by isspace()). This is for SQL conformance, as well
as consistency with other numeric types (e.g. oid, numeric).
Also refactor pg_atoi() to avoid looking at errno where not
necessary, and add a bunch of regression tests for the input
to these types.

this input will be rejected.
Also added a new error code for warnings about deprecated features,
and updated the regression tests.

for speed reasons; its result type also changes to int8. avg() on these
datatypes now accumulates the running sum in int8 for speed; but we still
deliver the final result as numeric, so that fractional accuracy is
preserved.
count() now counts and returns in int8, not int4. I am a little nervous
about this possibly breaking users' code, but there didn't seem to be
a strong sentiment for avoiding the problem. If we get complaints during
beta, we can change count back to int4 and add a "count8" aggregate.
For that matter, users can do it for themselves with a simple CREATE
AGGREGATE command; the int4inc function is still present, so no C hacking
is needed.
Also added max() and min() aggregates for OID that do proper unsigned
comparison, instead of piggybacking on int4 aggregates.
initdb forced.

for portability. Per discussion on pghackers around 9/16/00.

rather than just being aliases for int4in/int4out. Give type Oid a
full set of comparison operators that do proper unsigned comparison,
instead of reusing the int4 comparators. Since pg_dump is now doing
unsigned comparisons of OIDs, it is now *necessary* that we play by
the rules here. In fact, given that btoidcmp() has been doing unsigned
comparison for quite some time, it seems likely that we have index-
corruption problems in 7.0 and before once the Oid counter goes past
2G. Fixing these operators is a necessary step before we can think
about 8-byte Oid, too.

At this point I think it'd be possible to make float4 be pass-by-value
without too much work --- and float8 too on machines where Datum is
8 bytes. Something to try when the mood strikes, anyway.

WARNING: This is actually broken - we have self-deadlocks
due to concurrent changes in buffer management.
Vadim and me are working on it.

we'll get there one day.
Use `cat' to create aclocal.m4, not `aclocal'. Some people don't
have automake installed.
Only run the autoconf rule in the top-level GNUmakefile if the
invoker specified `make configure', don't run it automatically
because of CVS timestamp skew.

inputs have been converted to newstyle. This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters. Still
more to do for the Alpha port however.

no longer returns buffer pointer, can be gotten from scan;
descriptor; bootstrap can create multi-key indexes;
pg_procname index now is multi-key index; oidint2, oidint4, oidname
are gone (must be removed from regression tests); use System Cache
rather than sequential scan in many places; heap_modifytuple no
longer takes buffer parameter; remove unused buffer parameter in
a few other functions; oid8 is not index-able; remove some use of
single-character variable names; cleanup Buffer variables usage
and scan descriptor looping; cleaned up allocation and freeing of
tuples; 18k lines of diff;
