Tom Lane 8525419947 Don't try to trim "../" in join_path_components(). 
join_path_components() tried to remove leading ".." components from its
tail argument, but it was not nearly bright enough to do so correctly
unless the head argument was (a) absolute and (b) canonicalized.
Rather than try to fix that logic, let's just get rid of it: there is no
correctness reason to remove "..", and cosmetic concerns can be taken
care of by a subsequent canonicalize_path() call.  Per bug #6715 from
Greg Davidson.

Back-patch to all supported branches.  It appears that pre-9.2, this
function is only used with absolute paths as head arguments, which is why
we'd not noticed the breakage before.  However, third-party code might be
expecting this function to work in more general cases, so it seems wise
to back-patch.

In HEAD and 9.2, also make some minor cosmetic improvements to callers.

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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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/.
