Version 1.6.0 of the PostgreSQL Partition Manager extension (pg_partman) was released with a new custom time partitioning feature. Any partition interval ranging from 1 second to the min/max timestamp values is now supported. You can now also designate the starting partition during initial setup.
A blog post giving examples of these new features can be found here http://www.keithf4.com/partitioning-with-custom-time-intervals/ The extension is maintained on github and can be downloaded there or from pgxn. https://github.com/keithf4/pg_partman http://pgxn.org/dist/pg_partman/ -- Keith Fiske Database Administrator OmniTI Computer Consulting, Inc. http://www.keithf4.com
