Tom Lane 4b34624daa Code review for commands/statscmds.c. 
Fix machine-dependent sorting of column numbers.  (Odd behavior
would only materialize for column numbers above 255, but that's
certainly legal.)

Fix poor choice of SQLSTATE for some errors, and improve error message
wording.  (Notably, "is not a scalar type" is a totally misleading way
to explain "does not have a default btree opclass".)

Avoid taking AccessExclusiveLock on the associated relation during DROP
STATISTICS.  That's neither necessary nor desirable, and it could easily
have put us into situations where DROP fails (compare commit 68ea2b7f9).

Adjust/improve comments.

David Rowley 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:

	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/.
