Tom Lane bcc6c4c291 Fix performance issue in EXPLAIN (ANALYZE, TIMING OFF). Commit `af7914c662`, which added the TIMING option to EXPLAIN, had an oversight: if the TIMING option is disabled then control in InstrStartNode() goes through an elog(DEBUG2) call, which typically does nothing but takes a noticeable amount of time to do it. Tweak the logic to avoid that. In HEAD, also change the elog(DEBUG2)'s in instrument.c to elog(ERROR). It's not very clear why they weren't like that to begin with, but this episode shows that not complaining more vociferously about misuse is likely to do little except allow bugs to remain hidden. While at it, adjust some code that was making possibly-dangerous assumptions about flag bits being in the rightmost byte of the instrument_options word. Problem reported by Pavel Stehule (via Tomas Vondra).		2013-02-07 22:53:00 -05:00

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/.
