+# This script runs the Postgres regression tests with all useful combinations
+# of the backend options that disable various query plan types.  If the
+# results are not all the same, it may indicate a bug in a particular
+# plan type, or perhaps just a regression test whose results aren't fully
+# determinate (eg, due to lack of an ORDER BY keyword).
+#
+# Run this in the src/test/regress directory, after doing the usual setup
+# for a regular regression test, ie, "make clean all" (you should be ready
+# to do "make runtest").
+#
+# The backend option switches that we use here are:
+#	-fs	disable sequential scans
+#	-fi	disable index scans
+#	-fn	disable nestloop joins
+#	-fm	disable merge joins
+#	-fh	disable hash joins
+# Only mergejoin and hashjoin are really guaranteed to turn off; the others
+# just bias the optimizer's cost calculations heavily against that choice.
+# There's no point in trying to turn off both scan types or all three join
+# types simultaneously; ergo, we have 3*7 = 21 interesting combinations.
+#
+# Note that this will take *more than* 21 times longer than a regular
+# regression test, since we are preventing the system from using the most
+# efficient available query plans!  Have patience.

+# Select make to use --- default 'make', can be overridden by env var
+MAKE="${MAKE:-make}"
+
+# If PGOPTIONS is already defined, we'll add the -f switches to it.
