Tom Lane bf429cebd0 Improve git_changelog as per discussion with Robert Haas.
1. Resurrect the behavior where old commits on master will have Branch:
labels for branches sprouted after the commit was made.  I'm still
dubious about this mode, but if you want it, say --post-date or -p.

2. Annotate the Branch: labels with the release or branch in which the
commit was publicly released.  For example, on a release branch you could
see
Branch: REL8_3_STABLE Release: REL8_3_2 [92c3a8004] 2008-03-29 00:15:37 +0000
showing that the fix was released in 8.3.2.  Commits on master will
usually instead have notes like
Branch: master Release: REL8_4_BR [6fc9d4272] 2008-03-29 00:15:28 +0000
showing that this commit is ancestral to release branches 8.4 and later.
If no Release: marker appears, the commit hasn't yet made it into any
release.

3. Add support for release branches older than 7.4.

4. The implementation is improved by running git log on each branch only
back to where the branch sprouts from master.  This saves a good deal
of time (about 50% of the runtime when generating the complete history).
We generate the post-date-mode tags via a direct understanding that
they should be applied to master commits made before the branch sprouted,
rather than backing into them via matching (which isn't any too
reliable when people used identical log messages for successive commits).

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:

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/.
