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.

Introduced in PostgreSQL 8.1, the AUTOVACUUM daemon is an optional feature that automatically vacuums the database so that you don't have to manually run the  VACUUM statement . The AUTOVACUUM daemon is enabled in the default configuration. The AUTOVACUUM daemon is made up of multiple processes that reclaim storage by removing obsolete data or tuples from the database. It checks for tables that have a significant number of inserted, updated, or deleted records and vacuums these tables based on the configuration settings below. Default Settings The AUTOVACUUM settings for PostgreSQL can be found in the  postgresql.conf  file and control when/how the daemon runs.

PostgreSQL Pgbadger Installation On Linux

Image
PgBadger is a tool that analyzes PostgreSQL log files and generates reports on execution of SQL and server operation. Statistical reports analyzed from a number of perspectives can be useful not only for grasping the usual database operation but also as a hint for performance improvement. The report output by pgBadger has the following features. Graph output in HTML format Many statistical objects Daily, Weekly unit creation possible 1.Graph output in HTML format Many of the analysis results can be displayed in graph form by outputting the report in HTML format (output in text format or JSON format is also possible). By analyzing the log information graphed, it is much more prospective for people to see than the raw log data. So, if you do not need to handle it with another tool separately, we recommend report output in HTML format. 2.Many statistical objects A lot of data useful for database performance analysis is output in the report as shown below.
