- pg_partmaint 0.1.2
- Extension to manage partitioned tables by time or ID
Recommended: pg_jobmon (>0.3.0). 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;
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>';
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 3 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.
