README

PG Partition Manager

pg_partman is an extension to create and manage both time-based and serial-based table partition sets. Child table & trigger function creation is all managed by the extension itself. Tables with existing data can also have their data partitioned in easily managed smaller batches. Optional retention policy can automatically drop partitions no longer needed.

INSTALLATION

Recommended: pg_jobmon (>=1.0.0). PG Job Monitor will automatically be used if it is installed.

In directory where you downloaded mimeo to run

make
make install

Log into PostgreSQL and run the following commands. Schema can be whatever you wish, but it cannot be changed after installation.

CREATE SCHEMA partman;
CREATE EXTENSION pg_partman SCHEMA partman;

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.

ALTER EXTENSION pg_partman UPDATE TO '<latest version>';

EXAMPLE

First create a parent table with an appropriate column type for the partitioning you will do. Here's one with a columns that can be used for either

CREATE schema test;
CREATE TABLE test.part_test (col1 serial, col2 text, col3 timestamptz DEFAULT now());

If you're looking to do time-based partitioning, and will only be inserting new data, time-static is an appropriate choice. Just run the create_parent() function with the appropriate parameters

SELECT part.create_parent('test.part_test', 'col3', 'time-static', 'daily');

This will turn your table into a parent table and premake 4 future partitions. To make new partitions for time-based partitioning, run the run_maintenance() function. Ideally, you'd run this as a cronjob to keep new partitions premade in preparation of new data.

This should be enough to get you started. Please see the pg_partman.md file in the doc folder for more information on the types of partitioning supported and what the parameters in the create_parent() function mean.
