of XLogInsert had the same sort of checkpoint interlock problem as RecordTransactionCommit, and indeed I found some. Btree index build and ALTER TABLE SET TABLESPACE write data outside the friendly confines of the buffer manager, and therefore they have to take their own responsibility for checkpoint interlock. The easiest solution seems to be to force smgrimmedsync at the end of the index build or table copy, even when the operation is being WAL-logged. This is sufficient since the new index or table will be of interest to no one if we don't get as far as committing the current transaction. |

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 and Tcl. The JDBC, ODBC, C++, and Python interfaces have been moved to the PostgreSQL Projects Web Site at http://gborg.postgresql.org for separate maintenance. A Perl DBI/DBD driver is available from CPAN. 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/.
