Add skip-empty-xacts option to test_decoding for use in the regression tests.
The regression tests for contrib/test_decoding regularly failed onpostgres instances that were very slow. Either because the hardwareitself was slow or because very expensive debugging options likeCLOBBER_CACHE_ALWAYS were used.The reason they failed was just that some additional transactions weredecoded. Analyze and vacuum, triggered by autovac.To fix just add a option to test_decoding to only display transactionsin which a change was actually displayed. That's not pretty because itremoves information from the tests; but better than constantly failingtests in very likely harmless ways.Backpatch to 9.4 where logical decoding was introduced.Discussion: 20140629142511.GA26930@awork2.anarazel.de
