+   The source distribution also contains regression tests of the static
+   behaviour of Hot Standby. These tests require a running primary server
+   and a running standby server that is accepting new WAL changes from the
+   primary using either file-based log shipping or streaming replication.
+   Those servers are not automatically created for you, nor is the setup
+   documented here. Please check the various sections of the docs already
+   devoted to the required commands and related issues.

+   First create a database called "regression" on the primary.
+<screen>
+psql -h primary -c "CREATE DATABASE regression"
+</screen>
+   Next, run a preparatory script on the primary in the regression database:
+   <filename>src/test/regress/sql/hs_primary_setup.sql</filename>, and
+   allow for the changes to propagate to the standby, for example
+<screen>
+psql -h primary -f src/test/regress/sql/hs_primary_setup.sql regression
+</screen>
+   Now confirm that the default connection for the tester is the standby
+   server under test and then run standbycheck from the regression
+   directory.
