See below for further explanations on these configuration values. And for non-native partitioning, set the optimize_trigger value to efficiently handle your most frequent data range. It is recommended that you set the premake value high enough to encompass your expected data range being inserted. This may cause intervening data to go to the parent/default as stated above if no child table exists. This means that if you put 'future' data in, newly created tables will be based off that value. Note that future child table creation is based on the data currently in the partition set. A default partition for native is only available in PostgreSQL 11+. And also better than throwing an error and losing the data! For native partitioning, inserting data with no relevant child causes an error in PostgreSQL 10. That is much easier than having to clean up potentially hundreds or thousands of unwanted partitions. The check_default() function provides monitoring for any data getting inserted into the parent/default table and the partition_data_* set of functions can easily partition that data for you if it is valid data. This is preferred over automatically creating new partitions to match that data since a mistake that is causing non-partitioned data to be inserted could cause a lot of unwanted child tables to be made as well as contention due to transactional DDL.

Version 4.0.0 adds even more native support for features introduced in PG11 (easier index/fk inheritance, default partition).įor non-native partitioning, if you attempt to insert data into a partition set that contains data for a partition that does not exist, that data will be placed into the set's parent table. A trigger function is no longer necessary in native partitioning, but automatic child table creation is not handled natively, which is where this extension comes into play. Some features of this extension have been expanded upon in the author's blog - Īs of version 3.0.1, this extension will support the native partitioning methods that were introduced in PostgreSQL 10. Updates that would move a value from one partition to another are only supported in PostgreSQL 11 native partitioning. Currently the trigger functions only handle inserts to the parent table. It has many options, but usually only a few are needed, so it's much easier to use than it may first appear (and definitely easier than implementing it yourself). PostgreSQL Partition Manager is an extension to help make managing time or serial id based table partitioning easier. PostgreSQL Partition Manager Extension ( pg_partman) About
