Steps to Setup Database Link in PostgreSQL Database Link in PostgreSQL enables a database user to access a table present on a different PostgreSQL cluster. It provides a functionality in PostgreSQL similar to that of DB Link in Oracle, Linked Server in SQL Server and Federated Table in MySQL. In previous post we saw How to
Steps to Setup a Foreign Data Wrapper(postgres_fdw) in PostgreSQL A foreign data wrapper (postgres_fdw) is an extension available in PostgreSQL that allows you to access a table or schema in one PostgreSQL database from another PostgreSQL DB. For this demonstration, we’ll use the databases local_db and remote_db. We will access a table employee in remote_db
Steps to create a Database Link from Oracle to PostgreSQL Nowadays many companies are using a mix of RDBMS system for example, some instances are running on Oracle and other instances are running on PostgreSQL, and if we want to access data we need to do it using a heterogeneous connection. Heterogeneous connections allow us
Setup Logical replication using pglogical in PostgreSQL In the recent two blogs, we discuss built-in options like Streaming replication Click here to read more and Logical replication Click here to read more. In this blog, we will use pglogical extension to setup logical streaming replication for PostgreSQL. The pglogical extension provides logical streaming replication for PostgreSQL, using
Configure PgBouncer for PostgreSQL PostgreSQL has a heavyweight connection handling architecture. For each incoming connection, the postmaster forks out a new process called as backend process to handle it. While this design provides better stability and isolation, it does not make it particularly efficient at handling short-lived connections. A new Postgres client connection involves TCP
Backups from the Standby Server using pgBackRest in PostgreSQL In the previous blog, we have configured Streaming Replication Cluster using pgBackRest Click here to read more. We will use the same PostgreSQL cluster to show How we can take a backup from Standby Cluster using pgBackRest. Below are the high-level steps which we will
