It is very important to know a fact that PostgreSQL community does not support bug fixes and security fixes for older PostgreSQL versions. Currently, community only supports PostgreSQL versions starting from 9.4. So, if your database server is on 9.3 or older, you would see no bug fixes or security patches. Several benchmarks proves that the performance of a PostgreSQL database increases with each version upgrade. Maintenance activities like autovacuum, Optimizer enhancements, new features like parallel query, declarative partitioning, etc. are implemented in the latest versions. Each new version includes a list of several features to improve the experience of working with PostgreSQL. So, it is recommended to have PostgreSQL upgraded to the latest release always. This talk is focussed towards demonstration of the 3 methods using which a PostgreSQL server can be upgraded from any version >= 8.3 to a latest release, with a seamless downtime.
Following topics will be discussed during this talk -
- 1. pg_upgrade and multiple replication methods such as pglogical and Slony for replication to a newer version.
- 2. What are the prerequisites you should take before proceeding with an upgrade.
- 3. HA Solutions and Backup strategy you may use for newer releases.
- 4. How future upgrades are made easy using Logical Replication and Logical Decoding.
