In the "Differential code coverage between 16 and HEAD" thread, Andres pointed out that there wasn't test case coverage for pg_combinebackup's code to handle files in tablespaces. I looked at adding that, and as nobody could possibly have predicted, found a bug.
Here's a 2-patch series to (1) enhance PostgreSQL::Test::Utils::init_from_backup to handle tablespaces and then (2) fix the bug in pg_combinebackup and add test coverage using the facilities from the first patch. -- Robert Haas EDB: http://www.enterprisedb.com
