Peter Eisentraut 67235209ca Don't cast off_t to 32-bit type for output, bug fix
off_t is most likely a 64-bit integer, so casting it to a 32-bit type
for output could lose data.  There are more issues like this in the
tree, but this is an instance where this could actually happen in
practice, since base backups are routinely larger than 4 GB.  So this
is separated out as a bug fix.

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.  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.
