This patch addresses the problem that applications currently have to extract object names from possibly-localized textual error messages, if they want to know for example which index caused a UNIQUE_VIOLATION failure. It adds new error message fields to the wire protocol, which can carry the name of a table, table column, data type, or constraint associated with the error. (Since the protocol spec has always instructed clients to ignore unrecognized field types, this should not create any compatibility problem.) Support for providing these new fields has been added to just a limited set of error reports (mainly, those in the "integrity constraint violation" SQLSTATE class), but we will doubtless add them to more calls in future. Pavel Stehule, reviewed and extensively revised by Peter Geoghegan, with additional hacking by Tom Lane. |
