Tom Lane d0a585c699 Fix assorted breakage in to_char()'s OF format option.
In HEAD, fix incorrect field width for hours part of OF when tm_gmtoff is
negative.  This was introduced by commit 2d87eedc1d as a result of
falsely applying a pattern that's correct when + signs are omitted, which
is not the case for OF.

In 9.4, fix missing abs() call that allowed a sign to be attached to the
minutes part of OF.  This was fixed in 9.5 by 9b43d73b3f, but for
inscrutable reasons not back-patched.

In all three versions, ensure that the sign of tm_gmtoff is correctly
reported even when the GMT offset is less than 1 hour.

Add regression tests, which evidently we desperately need here.

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.
