Tom Lane 3152bf722f Fix bugs with parsing signed hh:mm and hh:mm:ss fields in interval input. 
DecodeInterval() failed to honor the "range" parameter (the special SQL
syntax for indicating which fields appear in the literal string) if the
time was signed.  This seems inappropriate, so make it work like the
not-signed case.  The inconsistency was introduced in my commit
f867339c01, which as noted in its log message
was only really focused on making SQL-compliant literals work per spec.
Including a sign here is not per spec, but if we're going to allow it
then it's reasonable to expect it to work like the not-signed case.

Also, remove bogus setting of tmask, which caused subsequent processing to
think that what had been given was a timezone and not an hh:mm(:ss) field,
thus confusing checks for redundant fields.  This seems to be an aboriginal
mistake in Lockhart's commit 2cf1642461.

Add regression test cases to illustrate the changed behaviors.

Back-patch as far as 8.4, where support for spec-compliant interval
literals was added.

Range problem reported and diagnosed by Amit Kapila, tmask problem by me.

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/.
