A great practice to ensure you’re using as little storage as possible is to consistently monitor the number of dead tuples in each table.This is the first step towards putting together an efficient PostgreSQL

A few weeks back, I discussed how Transparent Data Encryption safeguards your data even in case an attacker gets hold of your files. So this week I would like to talk about how PostgreSQL maps database objects into actual files. Let's dive in. A quick recap In mylast blog postI showed...
As a proud owner of a PostgreSQL database, you will inevitably have to experience and manage bloat, which is a product of PostgreSQL’s storage implementation for multi-version concurrency control. Concurrency is achieved by creating different versions of tuples as...
During the VACUUM run, which may take hours if the database is big, the database is, from a production standpoint, practically dead. Please note: in PostgreSQL version 7.2, basic vacuuming no longer locks tables, thus allowing normal user access during the vacuum. A new VACUUM FULL command...
Azure Database for PostgreSQLusers, you get the benefit ofQuery Store. Query Store is a more performant way of getting a comprehensive historical view of statistics for all queries. If you’re going to use statement logging because you need historical information on your Postgres q...

As discussed earlier, in a regular insert, there is no duplicate key pre-check before attempting to insert the tuple into the heap. Therefore, if it’s a duplicate value, it’s similar to first inserting a row and then deleting it. The result is a dead tuple, w...
You’ll configure Logstash to watch over three system databases in PostgreSQL, namely: pg_stat_database: provides statistics about each database, including its name, number of connections, transactions, rollbacks, rows returned by querying the database, deadlocks, and...
