+# Logical replication tests for temporal tables
+#
+# A table can use a temporal PRIMARY KEY or UNIQUE index as its REPLICA IDENTITY.
+# This is a GiST index (not B-tree) and its last element uses WITHOUT OVERLAPS.
+# That element restricts other rows with overlaps semantics instead of equality,
+# but it is always at least as restrictive as a normal non-null unique index.
+# Therefore we can still apply logical decoding messages to the subscriber.
