Tom Lane 6d776522d2 Document changes in large-object privilege checking. 
Commit 5ecc0d738 removed the hard-wired superuser checks in lo_import
and lo_export in favor of protecting them with SQL permissions, but
failed to adjust the documentation to match.  Fix that, and add a
<caution> paragraph pointing out the nontrivial security hazards
involved with actually granting such permissions.  (It's still better
than ALLOW_DANGEROUS_LO_FUNCTIONS, though.)

Also, commit ae20b23a9 caused large object read/write privilege to
be checked during lo_open() rather than in the actual read or write
calls.  Document that.

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/.
