Tom Lane d5ab79d815 Make pg_dump's table of object-type priorities more maintainable. 
Wedging a new object type into this table has historically required
manually renumbering a lot of existing entries.  (Although it appears
that some people got lazy and re-used the priority level of an
existing object type, even if it wasn't particularly related.)
We can let the compiler do the counting by inventing an enum type that
lists the desired priority levels in order.  Now, if you want to add
or remove a priority level, that's a one-liner.

This patch is not purely cosmetic, because I split apart the priorities
of DO_COLLATION and DO_TRANSFORM, as well as those of DO_ACCESS_METHOD
and DO_OPERATOR, which look to me to have been merged out of expediency
rather than because it was a good idea.  Shell types continue to be
sorted interchangeably with full types, and opclasses interchangeably
with opfamilies.

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/.
