If it fails to open a new log file, the syslogger assumes there's something wrong with its parameters (such as log_directory), and stops attempting automatic time-based or size-based log file rotations. Sending it SIGHUP is supposed to start that up again. However, the original coding for that was really bogus, involving clobbering a couple of GUC variables and hoping that SIGHUP processing would restore them. Get rid of that technique in favor of maintaining a separate flag showing we've turned rotation off. Per report from Mark Kirkwood. Also, the syslogger will automatically attempt to create the log_directory directory if it doesn't exist, but that was only happening at startup. For consistency and ease of use, it should do the same whenever the value of log_directory is changed by SIGHUP. Back-patch to all supported branches. |

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.
