+	* doc/schema/postgresql.sql: Dropped constraint that enforces the
+	  uniquness of km and river. This is violated because there are
+	  more than one sounding in different year at the same km of a river.
+	  Added column 'description' to the cross section table to make it
+	  human readable.
+
+	  To update existing databases:
+
+		ALTER TABLE cross_sections DROP CONSTRAINT cross_sections_km_key;
+		ALTER TABLE cross_sections ADD COLUMN description VARCHAR(256);
+
+	* src/main/java/de/intevation/flys/model/CrossSection.java:
+	  Added the description column to the Hibernate model.
