Peter Geoghegan e83ebfe6d7 Have VACUUM warn on relfrozenxid "in the future". 
Commits 74cf7d46 and a61daa14 fixed pg_upgrade bugs involving oversights
in how relfrozenxid or relminmxid are carried forward or initialized.
Corruption caused by bugs of this nature was ameliorated by commit
78db307bb2, which taught VACUUM to always overwrite existing invalid
relfrozenxid or relminmxid values that are apparently "in the future".

Extend that work now by showing a warning in the event of overwriting
either relfrozenxid or relminmxid due to an existing value that is "in
the future".  There is probably a decent chance that the sanity checks
added by commit 699bf7d05c will raise an error before VACUUM reaches
this point, but we shouldn't rely on that.

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/.
