Tom Lane b0c4a50bbb Instead of rechecking lossy index operators by putting them into the
regular qpqual ('filter condition'), add special-purpose code to
nodeIndexscan.c to recheck them.  This ends being almost no net addition
of code, because the removal of planner code balances out the extra
executor code, but it is significantly more efficient when a lossy
operator is involved in an OR indexscan.  The old implementation had
to recheck the entire indexqual in such cases.

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 a JDBC
driver.

The ODBC and C++ interfaces have been moved to the PostgreSQL Projects
Web Site at http://gborg.postgresql.org for separate maintenance.

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/.
