tuple header. The fix is based on the thought that HEAP_MOVED_IN is not needed any more as soon as HEAP_XMIN_COMMITTED has been set. So in tqual.c and vacuum.c the HEAP_MOVED bits are cleared when HEAP_XMIN_COMMITTED is set. Vacuum robustness is enhanced by rearranging ifs, so that we have a chance to elog(ERROR, ...) before an assertion fails. A new regression test is included. Manfred Koizar
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 several language bindings, including C, C++, Perl, Python, and Tcl, as well as drivers for JDBC and ODBC. 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 ftp://ftp.postgresql.org/pub/. For more information look at our web site located at http://www.postgresql.org/.
