This patch adds a 'location' column to the output of SHOW TABLE STATS / SHOW PARTITIONS. This helps users understand the effects of ALTER TABLE SET LOCATION commands, particularly for partitions, and is easier to identify than the output of DESCRIBE FORMATTED. Some existing tests in alter-table.test have been updated to include checking the location output before and after a SET LOCATION command. The tests in show.test have also been updated to check for the location; all other tests that use SHOW [TABLE STATS|PARTITIONS] use a generic regex to avoid overly verbose tests.
