Tom Lane 5ecc0d738e Restrict lo_import()/lo_export() via SQL permissions not hard-wired checks. 
While it's generally unwise to give permissions on these functions to
anyone but a superuser, we've been moving away from hard-wired permission
checks inside functions in favor of using the SQL permission system to
control access.  Bring lo_import() and lo_export() into compliance with
that approach.

In particular, this removes the manual configuration option
ALLOW_DANGEROUS_LO_FUNCTIONS.  That dates back to 1999 (commit 4cd4a54c8);
it's unlikely anyone has used it in many years.  Moreover, if you really
want such behavior, now you can get it with GRANT ... TO PUBLIC instead.

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/.
