Heikki Linnakangas 7cbee7c0a1 At promotion, don't leave behind a partial segment on the old timeline. 
With commit de768844, a copy of the partial segment was archived with the
.partial suffix, but the original file was still left in pg_xlog, so it
didn't actually solve the problems with archiving the partial segment that
it was supposed to solve. With this patch, the partial segment is renamed
rather than copied, so we only archive it with the .partial suffix.

Also be more robust in detecting if the last segment is already being
archived. Previously I used XLogArchiveIsBusy() for that, but that's not
quite right. With archive_mode='always', there might be a .ready file for
it, and we don't want to rename it to .partial in that case.

The old segment is needed until we're fully committed to the new timeline,
i.e. until we've written the end-of-recovery WAL record and updated the
min recovery point and timeline in the control file. So move the renaming
later in the startup sequence, after all that's been done.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	http://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
