Fujii Masao 7abc685974 Refactor WAL segment copying code. 
* Remove unused argument "dstfname" and related code from XLogFileCopy().

* Previously XLogFileCopy() returned a pstrdup'd string so that
InstallXLogFileSegment() used it later. Since the pstrdup'd string was never
free'd, there could be a risk of memory leak. It was almost harmless because
the startup process exited just after calling XLogFileCopy(), it existed.
This commit changes XLogFileCopy() so that it directly calls
InstallXLogFileSegment() and doesn't call pstrdup() at all. Which fixes that
memory leak problem.

* Extend InstallXLogFileSegment() so that the caller can specify the log level.
Which allows us to emit an error when InstallXLogFileSegment() fails a disk
file access like link() and rename(). Previously it was always logged with
LOG level and additionally needed to be logged with ERROR when we wanted
to treat it as an error.

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/.
