Alvaro Herrera a73491e5fe Fix crasher bug in array_position(s) ... array_position and its cousin array_positions were caching the element type equality function's FmgrInfo without being careful enough to put it in a long-lived context. This is obviously broken but it didn't matter in most cases; only when using arrays of records (involving record_eq) it becomes a problem. The fix is to ensure that the type's equality function's FmgrInfo is cached in the array_position's flinfo->fn_mcxt rather than the current memory context. Apart from record types, the only other case that seems complex enough to possibly cause the same problem are range types. I didn't find a way to reproduce the problem with those, so I only include the test case submitted with the bug report as regression test.
