connections by the superuser only. This patch replaces the last patch I sent a couple of days ago. It closes a connection that has not been authorised by a superuser if it would leave less than the GUC variable ReservedBackends (superuser_reserved_connections in postgres.conf) backend process slots free in the SISeg. This differs to the first patch which only reserved the last ReservedBackends slots in the procState array. This has made the free slot test more expensive due to the use of a lock. After thinking about a comment on the first patch I've also made it a fatal error if the number of reserved slots is not less than the maximum number of connections. Nigel J. Andrews
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, Perl, Python, and Tcl, as well as drivers for JDBC. As of v7.3, the ODBC and C++ interfaces have been moved over to the PostgreSQL Projects WebSite @ http://gborg.postgresql.org. 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/.
