A range type whose element type has 'd' alignment must have 'd' alignment itself, else there is no guarantee that the element value can be used in-place. (Because range_deserialize uses att_align_pointer which forcibly aligns the given pointer, violations of this rule did not lead to SIGBUS but rather to garbage data being extracted, as in one of the added regression test cases.) Also, you can't put a toast pointer inside a range datum, since the referenced value could disappear with the range datum still present. For consistency with the handling of arrays and records, I also forced decompression of in-line-compressed bound values. It would work to store them as-is, but our policy is to avoid situations that might result in double compression. Add assorted regression tests for this, and bump catversion because of fixes to built-in pg_type entries. Also some marginal cleanup of inconsistent/unnecessary error checks. |

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. 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/.
