Adjust elog.c so that elog(FATAL) exits (including cases where ERROR is
promoted to FATAL) end in exit(1) not exit(0). Then change the postmaster to
allow exit(1) without a system-wide panic, but not for the startup subprocess
or the bgwriter. There were a couple of places that were using exit(1) to
deliberately force a system-wide panic; adjust these to be exit(2) instead.
This fixes the problem noted back in July that if the startup process exits
with elog(ERROR), the postmaster would think everything is hunky-dory and
proceed to start up. Alternative solutions such as trying to run the entire
startup process as a critical section seem less clean, primarily because of
the fact that a fair amount of startup code is shared by all postmaster
children in the EXEC_BACKEND case. We'd need an ugly special case somewhere
near the head of main.c to make it work if it's the child process's
responsibility to determine what happens; and what's the point when the
postmaster already treats different children differently?

When truncating a relation in-place (eg during VACUUM), do not try to unlink
any no-longer-needed segments; just truncate them to zero bytes and leave
the files in place for possible future re-use. This avoids problems when
the segments are re-used due to relation growth shortly after truncation.
Before, the bgwriter, and possibly other backends, could still be holding
open file references to the old segment files, and would write dirty blocks
into those files where they'd disappear from the view of other processes.

Repair problems with hash indexes that span multiple segments: the hash code's
preference for filling pages out-of-order tends to confuse the sanity checks
in md.c, as per report from Balazs Nagy in bug #2737. The fix is to ensure
that the smgr-level code always has the same idea of the logical EOF as the
hash index code does, by using ReadBuffer(P_NEW) where we are adding a single
page to the end of the index, and using smgrextend() to reserve a large batch
of pages when creating a new splitpoint. The patch is a bit ugly because it
avoids making any changes in md.c, which seems the most prudent approach for a
backpatchable beta-period fix. After 8.3 development opens, I'll take a look
at a cleaner but more invasive patch, in particular getting rid of the now
unnecessary hack to allow reading beyond EOF in mdread().
Backpatch as far as 7.4. The bug likely exists in 7.3 as well, but because
of the magnitude of the 7.3-to-7.4 changes in hash, the later-version patch
