Tom Lane 6753f6c419 Fix pg_dump's logic for eliding sequence limits that match the defaults. 
The previous coding here applied atoi() to strings that could represent
values too large to fit in an int.  If the overflowed value happened to
match one of the cases it was looking for, it would drop that limit
value from the output, leading to incorrect restoration of the sequence.

Avoid the unsafe behavior, and also make the logic cleaner by explicitly
calculating the default min/max values for the appropriate kind of
sequence.

Reported and patched by Alexey Bashtanov, though I whacked his patch
around a bit.  Back-patch to v10 where the faulty logic was added.

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:

	https://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.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
