===================== I suggested an improvement of the inserttable in the PyGreSQL interface already in January, but seemingly it was never implemented. I was told this is the right place to get patches in for PyGreSQL, so I'm reposting my patch here. I consider the inserttable methode essential in populating the database because of its benefits in performance compared to insert, so I think this patch is quite essential. The attachment is an improved version of the corresponding pg_inserttable function in pgmodule.c, which fixes the following problems: * The function raised exceptions because PyList_GetItem was used beyond the size of the list. This was checked by comparing the result with NULL, but the exception was not cleaned up, which could result in mysterious errors in the following Python code. Instead of clearing the exception using PyErr_Clear or something like that, I avoided throwing the exception at all by at first requesting the size of the list. Using this opportunity, I also checked the uniformity of the size of the rows passed in the lists/tuples. The function also accepts (and silently ignores) empty lists and sublists. * Python "None" values are now accepted and properly converted to PostgreSQL NULL values * The function now generates an error message in case of a line buffer overflow * It copes with tabulators, newlines and backslashes in strings now * Rewrote the buffer filling code which should now run faster by avoiding unnecessary string copy operations forth and back Christoph Zwerschke
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/.
