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.

properly.

real affect now.

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;

Allow varchar() to only store needed bytes.  Remove PALLOC,PALLOCTYPE,PFREE.  Clean up use of VARDATA.

Another PGINDENT run that changes variable indenting and case label indenting.  Also static variable indenting.

Subject: [HACKERS] linux/alpha patches

These patches lay the groundwork for a Linux/Alpha port.  The port doesn't
actually work unless you tweak the linker to put all the pointers in the
first 32 bits of the address space, but it's at least a start.  It
implements the test-and-set instruction in Alpha assembly, and also fixes
a lot of pointer-to-integer conversions, which is probably good anyway.
