PostgreSQL: Script to check the status of AutoVacuum for all Tables

This article is half-done without your Comment! *** Please share your thoughts via Comment ***

In this post, I am sharing a script for checking the status of AutoVacuum for all the PostgreSQL Tables.

If you don’t know about the MVCC architecture, you must visit the below article. Because of MVCC, we have to work on dead tuples which are generated by transactions in PostgreSQL.

What is Multi Version Concurrency Control (MVCC)

You can configure auto-vacuum on tables, but periodically you should check the status of it. Use below script for checking the status of Autovacuum.

    I have also run into issues where a small variation of a dplyr pipeline causes it to take a minute instead of milliseconds. filter() (especially in the presence of an active grouping) is the most common danger step. It should be obvious from my stumbling around that I am not a regular data.table user. The reason is most of my current contracting work has been with data living in Spark / Hadoop or PostgreSQL . So I have been working a lot on database first methodologies . You made a very good point on the the “land a column of boolean decisions to use later as a index. That is a very powerful and fast R pattern that I feel is still under-used and under-appreciated. For example: I use it here to invert permutations (combining it with the “write some indices on the left of an assignment trick). Vector notations are incredibly powerful and can do some things that are not convenient to express otherwise.
