Understanding Partition Elimination in PostgreSQL 11
This is Part-III for my series on Postgres Table partitioning. I’ll encourage you to also read Part-I and II on this topic.

Starting Postgres 10.x and onward, it is now possible to create declarative partitions.
In my previous post ‘postgresql-table-partitioning-part-i-implementation-using-inheritance‘, I discussed about implementing Partitioning in PostgreSQL using ‘Inheritance’. Up until PostgreSQL 9, it was only way to partition tables in PostgreSQL. It was simple to implement, however had some limitations like:

In earlier PostgreSQL versions, it was not possible to declare table partitions syntactically. Partitioning can be implemented using table inheritance. The inheritance approach involves creating a single parent table and multiple child tables (aka. Partitions) to hold data in each partition range.
In this post, I’ll discuss the implementation of table partitions using inheritance. However before proceeding, let’s first understand why do we need partitioning? Continue reading “PostgreSQL Table Partitioning Part I – Implementation Using Inheritance”
