Add some checks that seem logically necessary, in particular let's make real sure that HS slave sessions cannot create temp tables. (If they did they would think that temp tables belonging to the master's session with the same BackendId were theirs. We *must* not allow myTempNamespace to become set in a slave session.) Change setval() and nextval() so that they are only allowed on temp sequences in a read-only transaction. This seems consistent with what we allow for table modifications in read-only transactions. Since an HS slave can't have a temp sequence, this also provides a nicer cure for the setval PANIC reported by Erik Rijkers. Make the error messages more uniform, and have them mention the specific command being complained of. This seems worth the trifling amount of extra code, since people are likely to see such messages a lot more than before. |

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/.
