# rhdb-explain(1)

A tool for visualizing the output of the PostgreSQL EXPLAIN command

## NAME

rhdb-explain - A tool for visualizing the output of the PostgreSQL EXPLAIN command

## SYNOPSIS

**rhdb-explain**

## DESCRIPTION

This manual page documents briefly the program **rhdb-explain**.

This manual page was written for the Debian distribution because the original program does not have a manual page.

**rhdb-explain** is Visual Explain, an interactive tool for visualizing the output of the PostgreSQL  **EXPLAIN** and **EXPLAIN ANALYZE** commands. **EXPLAIN** and **EXPLAIN ANALYZE** show the users the query plan that a PostgreSQL backend produces for a given optimizable query. The default form of this plan is a plain-text tree, which, while easy to read for simple queries, becomes progressilvely more difficult to interpret as query complexity increases. By visualizing the text output of **EXPLAIN**/**EXPLAIN ANALYZE** in an appropriate manner, the difficulty of interpreting query plans drops significantly.
