Formerly, if "psql -o foo" failed to open the output file "foo", it would print an error message but then carry on as though -o had not been specified at all. This seems contrary to expectation: a program that cannot open its output file normally fails altogether. Make psql do exit(1) after reporting the error. If "\o foo" failed to open "foo", it would print an error message but then reset the output file to stdout, as if the argument had been omitted. This is likewise pretty surprising behavior. Make it keep the previous output state, instead. psql keeps SIGPIPE interrupts disabled when it is writing to a pipe, either a pipe specified by -o/\o or a transient pipe opened for purposes such as using a pager on query output. The logic for this was too simple and could sometimes re-enable SIGPIPE when a -o pipe was still active, thus possibly leading to an unexpected psql crash later. Fixing the last point required getting rid of the kluge in PrintQueryTuples and ExecQueryUsingCursor whereby they'd transiently change the global queryFout state, but that seems like good cleanup anyway. Back-patch to 9.5 but not further; these are minor-enough issues that changing the behavior in stable branches doesn't seem appropriate.

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. 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.
