Tom Lane 6b45e3b7aa Arrange to generate different random sequences in the different child processes of a pgbench run, when we are using -j > 1 and are emulating threads via fork(). Otherwise the children all inherit the same random sequence state and produce the same random-number sequence. In the threaded case the different threads will share one RNG state, so they will produce different subsets of one sequence, which is maybe more correlated than a purist would like but will not be "the same". So we leave that case alone. First noticed by Takahiro Itagaki, and is also part of the explanation for the pgbench misbehavior recently reported by Jaime Casanova.		2009-12-11 21:50:06 +00:00

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/.
