/*
 * JIRA ticket reference: WT-2592
 * Test case description: This is an adaptation of the join parts of
 * ex_schema.c, but written as a test. Though we have join tests in the
 * Python test suite, the Python API uses raw mode for cursors, so errors
 * that are specific to non-raw mode are undetected in Python.
 * Failure mode: The failure seen in WT-2592 was that no items were returned
 * by a join.
