PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Changes between all PostgreSQL releases are recorded in the file HISTORY. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.

postgres_fdw tended to say "unknown error" if it tried to execute a command on an already-dead connection, because some paths in libpq just return a null PGresult for such cases. Out-of-memory might result in that, too. To fix, pass the PGconn to pgfdw_report_error, and look at its PQerrorMessage() string if we can't get anything out of the PGresult. Also, fix the transaction-exit logic to reliably drop a dead connection. It was attempting to do that already, but it assumed that only connection cache entries with xact_depth > 0 needed to be examined. The folly in that is that if we fail while issuing START TRANSACTION, we'll not have bumped xact_depth. (At least for the case I was testing, this fix masks the other problem; but it still seems like a good idea to have the PGconn fallback logic.) Per investigation of bug #9087 from Craig Lucas. Backpatch to 9.3 where this code was introduced.
