'volatile' pointers to access those structures, so that optimizing compilers will not decide to move the structure accesses outside of the spinlock-acquire-to-spinlock-release sequence. There are no known bugs in these uses at present, but based on bad experience with lwlock.c, it seems prudent to ensure that we protect these other uses too. Per pghackers discussion around 12-Dec. (Note: it should not be necessary to worry about structures protected by LWLocks, since the LWLock acquire and release operations are not inline macros.) |

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/.
