Except when compiling with EXEC_BACKEND, we'll now allocate only a tiny amount of System V shared memory (as an interlock to protect the data directory) and allocate the rest as anonymous shared memory via mmap. This will hopefully spare most users the hassle of adjusting operating system parameters before being able to start PostgreSQL with a reasonable value for shared_buffers. There are a bunch of documentation updates needed here, and we might need to adjust some of the HINT messages related to shared memory as well. But it's not 100% clear how portable this is, so before we write the documentation, let's give it a spin on the buildfarm and see what turns red. |

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 C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download 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 http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
