Tom Lane b82a7be603 Change pg_seclabel.provider and pg_shseclabel.provider to type "name".
These were "text", but that's a bad idea because it has collation-dependent
ordering.  No index in template0 should have collation-dependent ordering,
especially not indexes on shared catalogs.  There was general agreement
that provider names don't need to be longer than other identifiers, so we
can fix this at a small waste of table space by changing from text to name.

There's no way to fix the problem in the back branches, but we can hope
that security labels don't yet have widespread-enough usage to make it
urgent to fix.

There needs to be a regression sanity test to prevent us from making this
same mistake again; but before putting that in, we'll need to get rid of
similar brain fade in the recently-added pg_replication_origin catalog.

Note: for lack of a suitable testing environment, I've not really exercised
this change.  I trust the buildfarm will show up any mistakes.

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:

	http://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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
