+# Test driver for pg_rewind. Each test consists of a cycle where a new cluster

+# promoted, and finally pg_rewind is used to rewind the old master, using the

+#
+# To run a test, the test script (in t/ subdirectory) calls the functions
+# in this module. These functions should be called in this sequence:
+#
+# 1. setup_cluster - creates a PostgreSQL cluster that runs as the master
+#
+# 2. start_master - starts the master server
+#
+# 3. create_standby - runs pg_basebackup to initialize a standby server, and
+#    sets it up to follow the master.
+#
+# 4. promote_standby - runs "pg_ctl promote" to promote the standby server.
+# The old master keeps running.
+#
+# 5. run_pg_rewind - stops the old master (if it's still running) and runs
+# pg_rewind to synchronize it with the now-promoted standby server.
+#
+# 6. clean_rewind_test - stops both servers used in the test, if they're
+# still running.
+#
+# The test script can use the helper functions master_psql and standby_psql
+# to run psql against the master and standby servers, respectively.
