Building pg_journal
This is a PostgreSQL preload module for sending log messages directly to the systemd journal log.
This document explains how to build pg_journal. For usage documentation and
more info, please see the doc/pg_journal.md file or read the latest version
online.
Prerequisites:
- PostgreSQL version 9.2+ (earlier versions supported with a server patch).
- systemd v38 or newer with libsystemd-journal installed.
Quick start
To build and install this extension, simply run:
make
sudo make install
Then add the following line to your postgresql.conf:
shared_preload_libraries = 'pg_journal'
This change requires a restart of PostgreSQL.
Installation
To use this module, you need PostgreSQL version 9.2 or later. To use with
earlier versions, you need to patch and build your server manually. The
necessary patch is included under patches/logging-hooks.patch (courtesy of
Martin Pihlak).
To build and install this extension, simply run:
% make
% sudo make install
If you run into problems with building, see PostgreSQL wiki for troubleshooting
Once pg_journal is installed, you can enable it in your configuration file.
Find the postgresql.conf file (usually in your PostgreSQL data directory) and
add the following line:
shared_preload_libraries = 'pg_journal'
You need to restart your server for this to take effect. After that, log messages are automatically sent to journal.
