The initial implementation of pg_dump's --section option supposed that the existing --schema-only and --data-only options could be made equivalent to --section settings. This is wrong, though, due to dubious but long since set-in-stone decisions about where to dump SEQUENCE SET items, as seen in bug report from Martin Pitt. (And I'm not totally convinced there weren't other bugs, either.) Undo that coupling and instead drive --section filtering off current-section state tracked as we scan through the TOC list to call _tocEntryRequired(). To make sure those decisions don't shift around and hopefully save a few cycles, run _tocEntryRequired() only once per TOC entry and save the result in a new TOC field. This required minor rejiggering of ACL handling but also allows a far cleaner implementation of inhibit_data_for_failed_table. Also, to ensure that pg_dump and pg_restore have the same behavior with respect to the --section switches, add _tocEntryRequired() filtering to WriteToc() and WriteDataChunks(), rather than trying to implement section filtering in an entirely orthogonal way in dumpDumpableObject(). This required adjusting the handling of the special ENCODING and STDSTRINGS items, but they were pretty weird before anyway. Minor other code review for the patch, too. |

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/.
