pg_jobmon

pg_jobmon is a PostgreSQL extension designed to add autonomous logging capabilities to transactions and functions. The logging is done in a NON-TRANSACTIONAL method, so that if your function/transaction fails for any reason, any information written to that point will be kept in the log tables rather than rolled back.

For more information on how to use pg_jobmon, please see pg_jobmon/doc/pg_jobmon.md

INSTALLATION

Requirements: PostgreSQL 9.2+, dblink extension

In the directory where you downloaded pg_jobmon run

make
make install

Log into PostgreSQL and run the following commands: (Note: You can change the schema name to be whatever you wish, but it cannot be changed after installation.)

CREATE SCHEMA jobmon;
CREATE EXTENSION pg_jobmon SCHEMA jobmon;

This extension uses dblink to connect back to the same database that pg_jobmon is running in (this is how the non-transactional magic is done). To allow non-superusers to use dblink, you'll need to enter role credentials into the dblink_mapping_jobmon table that pg_jobmon installs.

INSERT INTO jobmon.dblink_mapping_jobmon (username, pwd) VALUES ('rolename', 'rolepassword');

Ensure you add the relevant line to the pg_hba.conf file for this role. It will be connecting back to the same postgres database locally.

# TYPE  DATABASE       USER            ADDRESS                 METHOD
local   dbname         rolename                                md5

The following permissions should be given to the above role (substitute relevant schema names as appropriate):

grant usage on schema jobmon to rolename;
grant usage on schema dblink to rolename;
grant select, insert, update, delete on all tables in schema jobmon to rolename;
grant execute on all functions in schema jobmon to rolename;
grant all on all sequences in schema jobmon to rolename;

If you're running PostgreSQL on a port other than the default (5432), you can also use the dblink_mapping_jobmon table to change the port that dblink will use.

INSERT INTO jobmon.dblink_mapping_jobmon (port) VALUES ('5999');

Be aware that the dblink_mapping_jobmon table can only have a single row, so if you're using a custom host, role or different port, you will need to enter those values within a single row. None of the columns are required, so just use the ones you need for your setup.

INSERT INTO jobmon.dblink_mapping_jobmon (host,username, pwd, port) VALUES ('host','rolename', 'rolepassword', '5999');

UPGRADE

Make sure all the upgrade scripts for the version you have installed up to the most recent version are in the $BASEDIR/share/extension folder.
