rather than deleting them only to have to create more. Steady state is 2*CHECKPOINT_SEGMENTS + WAL_FILES + 1 segment files, which will simply be renamed rather than constantly deleted and recreated. To make this safe, added current XLOG file/offset number to page header of XLOG pages, so that an un-overwritten page from an old incarnation of a logfile can be reliably told from a valid page. This change means that if you try to restart postmaster in a CVS-tip database after installing the change, you'll get a complaint about bad XLOG page magic number. If you don't want to initdb, run contrib/pg_resetxlog (and be sure you shut down the old postmaster cleanly). |

The PostgreSQL contrib tree ~~~~~~~~~~~~~~~~~~~~~~~~~~~ This subtree contains tools, modules, and examples that are not maintained as part of the core PostgreSQL system, mainly because they only address a limited audience or are too inelegant to be sold as an official feature. That, however, does not preclude their usefulness. Each subdirectory contains a README file with information about the module. Most items can be built with `gmake all' and installed with `gmake install' in the usual fashion, after you have run the `configure' script in the top-level directory. Some directories supply new user-defined functions, operators, or types. After you have installed the files you need to register the new entities in the database system by running the commands in the supplied .sql file. For example, $ psql -d dbname -f module.sql See the PostgreSQL documentation for more information about this procedure.
