+# Tests of prelocking-free execution of stored procedures.
+# Currently two properties of prelocking-free SP execution are checked:
+#  - It is possible to execute DDL statements in prelocking-free stored
+#    procedure
+#  - The same procedure can be called in prelocking-free mode and 
+#    in prelocked mode (from within a function).
