This follows my proposal of yesterday, namely that we try to recreate the previous state of the extension exactly, instead of allowing CREATE EXTENSION to run a SQL script that might create some entirely-incompatible on-disk state. In --binary-upgrade mode, pg_dump won't issue CREATE EXTENSION at all, but instead uses a kluge function provided by pg_upgrade_support to recreate the pg_extension row (and extension-level pg_depend entries) without creating any member objects. The member objects are then restored in the same way as if they weren't members, in particular using pg_upgrade's normal hacks to preserve OIDs that need to be preserved. Then, for each member object, ALTER EXTENSION ADD is issued to recreate the pg_depend entry that marks it as an extension member. In passing, fix breakage in pg_upgrade's enum-type support: somebody didn't fix it when the noise word VALUE got added to ALTER TYPE ADD. Also, rationalize parsetree representation of COMMENT ON DOMAIN and fix get_object_address() to allow OBJECT_DOMAIN. |

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. Changes between all PostgreSQL releases are recorded in the file HISTORY. 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/.
