Summary: Built-in logical replication and logical decoding were introduced in PostgreSQL 10. Over a period of time, more and more features are being implemented within logical replication. It is helpful when a selected list of tables needs to be replicated from multiple OLTP databases to a single OLAP database for reporting and analysis.
Summary: Streaming replication (physical replication), which is byte-by-byte replication, involves a continuous application of WAL records from Primary to Standby. As it uses a file-based log shipping method, it is one of the fastest replication methods when compared with logical replication or other trigger-based methods.
pg_basebackup is the built-in binary format backup tool available with PostgreSQL. Only the backups taken using
pg_basebackup can be used for point-in-time recovery and not
Summary: In the backing up a database cluster tutorial, we discussed how
pg_basebackup can be used to take a physical backup of the PostgreSQL cluster. We may restore this backup in various situations, such as creating a standby server in replication or recovering a database to a point in time. In this tutorial, we shall see the steps required to restore a backup taken using
Summary: Every 3 months, the PostgreSQL community releases minor version updates that are available for all the supported PostgreSQL versions. Let’s say that we are using PostgreSQL 13.1 but a new minor version, PostgreSQL 13.2, has been released. In this recipe, we shall see how a minor version upgrade can be performed when using PostgreSQL 13.
