Get rid of the code that attempted to funnel libxml2's memory allocations into palloc. We already knew from experience with the core xml datatype that trying to do this is simply not reliable. Unlike the core code, I did not bother adding a lot of PG_TRY/PG_CATCH logic to try to ensure that everything is cleaned up on error exit. Hence, we might leak some memory if one of these functions fails partway through. Given the deprecated status of this contrib module and the fact that errors partway through the functions shouldn't be too common, it doesn't seem worth worrying about. Also fix a separate bug in xpath_table, that it did the wrong things if given a result tuple descriptor with less than 2 columns. While such a case isn't very useful in practice, we shouldn't fail or stomp memory when it occurs. Add some simple regression tests based on all the reported crash cases that I have on hand. This should be back-patched, but let's see if the buildfarm likes it first. |

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.
