Tom Lane a4390abecf Reduce the range of OIDs reserved for genbki.pl. Commit `ab596105b` increased FirstBootstrapObjectId from 12000 to 13000, but we've had some push-back about that. It's worrisome to reduce the daylight between there and FirstNormalObjectId, because the number of OIDs consumed during initdb for collation objects is hard to predict. We can improve the situation by abandoning the assumption that these OIDs must be globally unique. It should be sufficient for them to be unique per-catalog. (Any code that's unhappy about that is broken anyway, since no more than per-catalog uniqueness can be guaranteed once the OID counter wraps around.) With that change, the largest OID assigned during genbki.pl (starting from a base of 10000) is a bit under 11000. This allows reverting FirstBootstrapObjectId to 12000 with reasonable confidence that that will be sufficient for many years to come. We are not, at this time, abandoning the expectation that hand-assigned OIDs (below 10000) are globally unique. Someday that'll likely be necessary, but the need seems years away still. This is late for v14, but it seems worth doing it now so that downstream software doesn't have to deal with the consequences of a change in FirstBootstrapObjectId. In any case, we already bought into forcing an initdb for beta2, so another catversion bump won't hurt. Discussion: https://postgr.es/m/1665197.1622065382@sss.pgh.pa.us		2021-05-27 15:55:08 -04:00

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/.
