cursors. Patch from Joachim Wieland, review and ediorialization by Neil Conway. The view lists cursors defined by DECLARE CURSOR, using SPI, or via the Bind message of the frontend/backend protocol. This means the view does not list the unnamed portal or the portal created to implement EXECUTE. Because we do list SPI portals, there might be more rows in this view than you might expect if you are using SPI implicitly (e.g. via a procedural language). Per recent discussion on -hackers, the query string included in the view for cursors defined by DECLARE CURSOR is based on debug_query_string. That means it is not accurate if multiple queries separated by semicolons are submitted as one query string. However, there doesn't seem a trivial fix for that: debug_query_string is better than nothing. I also changed SPI_cursor_open() to include the source text for the portal it creates: AFAICS there is no reason not to do this. Update the documentation and regression tests, bump the catversion.
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. The JDBC, ODBC, C++, Python, and Tcl interfaces have been moved to the PostgreSQL Projects Web Site at http://gborg.postgresql.org for separate maintenance. A Perl DBI/DBD driver is available from CPAN. 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/.
