In order to achieve High Availability (HA) in Postgres, we need to have at least one other standby replica that keeps up with the primary’s changes near-real-time. Using Postgres physical replication is the most common method to achieve this.

A practical guide to the SQL LATERAL JOIN. Solve complex SQL problems easily, with clear PostgreSQL examples and use cases.

Replication slots in Postgres keep track of how far consumers have read a replication stream. After a restart, consumers—​either Postgres read replicas or external tools for change data capture (CDC), like Debezium—resume reading from the last confirmed log sequence number (LSN) of their replication slot. The slot prevents the database from disposing of required log segments, allowing safe resumption after downtime. In this post, we are going to take a look at why Postgres replication slots don’t have one but two LSN-related attributes: restart_lsn and confirmed_flush_lsn. Understanding the difference between the two is crucial for troubleshooting replication issues, optimizing WAL retention, and avoiding common pitfalls in production environments.

While working with a legacy BBj PRO/5 database for a client, we needed to set up a new CMS with multitenancy requirements. We were dealing with a slew of foreign tables representing the PRO/5 data, and each of the tables had a column for designating which tenant they belonged to. Let's talk about how we leveraged ActiveSupport::CurrentAttributes to solve this problem!
