Change the rules for inherited CHECK constraints to be essentially the same
as those for inherited columns; that is, it's no longer allowed for a child
table to not have a check constraint matching one that exists on a parent.
This satisfies the principle of least surprise (rows selected from the parent
will always appear to meet its check constraints) and eliminates some
longstanding bogosity in pg_dump, which formerly had to guess about whether
check constraints were really inherited or not.
The implementation involves adding conislocal and coninhcount columns to
pg_constraint (paralleling attislocal and attinhcount in pg_attribute)
and refactoring various ALTER TABLE actions to be more like those for
columns.

Fix incorrect archive truncation point calculation in the %r recovery_command
parameter. This fixes bug 4137 reported by Wojciech Strzalka, where a WAL
file is deleted too early when starting the recovery of a warm standby server.
Also add a sanity check in pg_standby so that it will refuse to delete anything
earlier than the file being restored, and improve the debug message in case
nothing is deleted.

Provide for MSVC config equivalents of recently added configure options. Remove

with extension facilities such as aliases being proposed, it is a good time to

Remove the recently added USE_SEGMENTED_FILES option, and indeed remove all

doesn't seem to be much value in a "never segment" option as opposed to

configure-time switch to set the desired segment size in units of gigabytes.
