How to Get Table Size, Database Size, Indexes Size, schema Size, Tablespace Size, column Size in PostgreSQL Database

In this post, I am sharing few important function for finding the size of database, table and index in PostgreSQL. Finding object size in postgresql database is very important and common. Is it very useful to know the exact size occupied by the object at the tablespace. The object size in the following scripts is in GB. The scripts have been formatted to work very easily with PUTTY SQL Editor. 1. Checking table size excluding table dependency: SELECT pg_size_pretty(pg_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 238 MB (1 row) 2. Checking table size including table dependency: SELECT pg_size_pretty(pg_total_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 268 MB (1 row) 3. Finding individual postgresql database size SELECT pg_size_pretty(pg_database_size('db_name')); 4. Finding individual table size for postgresql database -including dependency index: SELECT pg_size_pretty(pg_total_rel...

PostgreSQL Barman (Backup and Recovery Manager)

Image
Barman  (Backup and Recovery Manager) is an open-source administration tool for disaster recovery of PostgreSQL servers written in Python. It allows your organisation to perform remote backups of multiple servers in business critical environments to reduce risk and help DBAs during the recovery phase. Barman  is distributed under GNU GPL 3 and maintained by 2ndQuadrant, a platinum sponsor of the  PostgreSQL project . IMPORTANT:  This manual assumes that you are familiar with theoretical disaster recovery concepts, and that you have a grasp of PostgreSQL fundamentals in terms of physical backup and disaster recovery. See section  “Before you start”  below for details. Introduction In a perfect world, there would be no need for a backup. However, it is important, especially in business environments, to be prepared for when the  “unexpected”  happens. In a database scenario, the unexpected could take any of the following forms: d...

PostgreSQL Sequence

A sequence in PostgreSQL is a database object that is essentially an automatically incrementing numeric value. For this reason, sequences are commonly known in other database products as auto-increment values. Sequences can be extremely useful in assigning non-random, unique identification numbers to tables that require such values. A sequence consists of a current numeric value, and a set of characteristics that determine how to automatically increment (or alternatively, decrement) that value upon use. Along with its current value, a sequence also includes a minimum value, a maximum value, a starting value, and the amount to increment the sequence by. This increment is usually 1, but may be any whole integer. In practice, sequences are not meant to be accessed directly. Instead, they are used through a set of functions built into PostgreSQL which either set, increment, or return the current value of the sequence. Creating a sequence Sequences are created with the CREAT...

How to Install pgAgent On windows

Image
Taking regular SQL database backup is one of the most important responsibilities of a database administrator. By setting up automatic database backup we can get rid of the additional overhead of doing it manually, every day, week or month. When it comes to PostgreSQL running in any Unix distributions or in Windows, there are at least two ways to do it. Using the built in CronJobs/ CronTabs in case of  Linux, and Windows scheduled tasks in Windows . Using PostgreSQL’s own scheduling agent,  pgAgent . Often DBAs tends to rely on CronTabs or Scheduled tasked because of the ease of use it offers. But there are several advantages if you use pgAgent instead. Though it takes a little effort to install pgAgent, it is much better than Cron jobs or Scheduled tasks. Why use pgAgent over CronJob: Compared to CronTab, PgAgent has the following advantages:  You can have multiple steps for a job without having to resort to a batch script. You can have multiple sched...
