The test did not wait for all the subscriptions to have caught up when dropping the subscription "tab_copy". In a slow environment, it could be possible for the replay of the COMMIT PREPARED transaction "mygid" to not be confirmed yet, causing one prepared transaction to be left around before moving to the next steps of the test. One failure noticed is a transaction found in pg_prepared_xacts for the cases where copy_data = false and two_phase = true, but there should be none after dropping the subscription. As an extra safety measure, a check is added before dropping the subscription, scanning pg_prepared_xacts to make sure that no prepared transactions are left once both subscriptions have caught up.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check". Check src/test/Makefile to see which tests get run automatically. authentication/ Tests for authentication (but see also below) examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level kerberos/ Tests for Kerberos/GSSAPI authentication and encryption ldap/ Tests for LDAP-based authentication locale/ Sanity checks for locale data, encodings, etc mb/ Tests for multibyte encoding (UTF-8) support modules/ Extensions used only or mainly for test purposes, generally not suitable for installing in production databases perl/ Infrastructure for Perl-based TAP tests recovery/ Test suite for recovery and replication regress/ PostgreSQL's main regression test suite, pg_regress ssl/ Tests to exercise and verify SSL certificate handling subscription/ Tests for logical replication
