Tom Lane a0854f1072 Avoid parsing catalog data twice during BKI file construction. 
In the wake of commit 5602265f7, we were doing duplicate-OID detection
quite inefficiently, by invoking duplicate_oids which does all the same
parsing of catalog headers and .dat files as genbki.pl does.  That adds
under half a second on modern machines, but quite a bit more on slow
buildfarm critters, so it seems worth avoiding.  Let's just extend
genbki.pl a little so it can also detect duplicate OIDs, and remove
the duplicate_oids call from the build process.

(This also means that duplicate OID detection will happen during
Windows builds, which AFAICS it didn't before.)

This makes the use-case for duplicate_oids a bit dubious, but it's
possible that people will still want to run that check without doing
a whole build run, so let's keep that script.

In passing, move down genbki.pl's creation of its temp output files
so that it doesn't happen until after we've done parsing and validation
of the input.  This avoids leaving a lot of clutter around after a
failure.

John Naylor and Tom Lane

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/.
