In the test_slot_timelines test module, we were abusing passing NULL values which was received as zeroes in x86, but this breaks in ARM (buildfarm member hamster) by crashing instead. Fix the breakage by marking these functions as STRICT; the InvalidXid value that was previously implicit in NULL values (on x86 at least) can now be passed as 0. Failing to follow the fmgr protocol to check for NULLs beforehand was causing ARM to fail, as evidenced by segmentation faults in buildfarm member hamster. In order to use the new functionality in the test script, use COALESCE in the right spot to avoid forwarding NULL values. This was diagnosed from the hamster crash by Craig Ringer, who also proposed a different patch (checking for NULL values explicitely in the C function code, and keeping the non-strictness in the C functions). I decided to go with this approach instead.
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. 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.
