small editorization by me - Brake the QueryItem struct into QueryOperator and QueryOperand. Type was really the only common field between them. QueryItem still exists, and is used in the TSQuery struct as before, but it's now a union of the two. Many other changes fell from that, like separation of pushval_asis function into pushValue, pushOperator and pushStop. - Moved some structs that were for internal use only from header files to the right .c-files. - Moved tsvector parser to a new tsvector_parser.c file. Parser code was about half of the size of tsvector.c, it's also used from tsquery.c, and it has some data structures of its own, so it seems better to separate it. Cleaned up the API so that TSVectorParserState is not accessed from outside tsvector_parser.c. - Separated enumerations (#defines, really) used for QueryItem.type field and as return codes from gettoken_query. It was just accidental code sharing. - Removed ParseQueryNode struct used internally by makepol and friends. push*-functions now construct QueryItems directly. - Changed int4 variables to just ints for variables like "i" or "array size", where the storage-size was not significant. |

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 including some of the more common listed below: C++ - http://thaiopensource.org/development/libpqxx/ JDBC - http://jdbc.postgresql.org ODBC - http://odbc.postgresql.org Perl - http://search.cpan.org/~dbdpg/ PHP - http://www.php.net Python - http://www.initd.org/ Ruby - http://ruby.scripting.ca/postgres/ Other language binding are available from a variety of contributing parties. PostgreSQL also has a great number of procedural languages available, a short but not complete list is below: PL/pgSQL - included in PostgreSQL source distribution PL/Perl - included in PostgreSQL source distribution PL/PHP - http://projects.commandprompt.com/projects/public/plphp PL/Python - included in PostgreSQL source distribution PL/Java - http://gborg.postgresql.org/project/pljava/projdisplay.php PL/Tcl - included in PostgreSQL source distribution 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/.
