+# Error Codes
+
+All messages emitted by Hyper are assigned five-character error codes
+that follow the SQL standard's conventions for “SQLSTATE” codes and
+their corresponding extensions from
+[PostgreSQL](https://www.postgresql.org/docs/current/errcodes-appendix.html).
+
+The following table lists all the error codes defined in Hyper:
