+# Concurrent update of a partition key and INSERT...ON CONFLICT DO NOTHING test
+#
+# This test tries to expose problems with the interaction between concurrent
+# sessions during an update of the partition key and INSERT...ON CONFLICT DO
+# NOTHING on a partitioned table.
+#
+# The convention here is that session 1 moves row from one partition to
+# another due update of the partition key and session 2 always ends up
+# inserting, and session 3 always ends up doing nothing.
+#
+# Note: This test is slightly resemble to insert-conflict-do-nothing test.
