+# SQL transform — how to provide calcite_connection_properties
+#
+# This example shows how to provide Calcite connection properties (for
+# example to enable PostgreSQL-specific functions) to a YAML pipeline.
+#
+# The connection properties can be provided under the top-level `options:`
+# key. Most of the time you can provide them as normal YAML mappings.
+# Some environments may expect a JSON-formatted string instead; both forms
+# are shown below.
