How To Fix pgreplay: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu pgreplay is provided by pgreplay package.

pgreplay is:

Reads a PostgreSQL log file (not a WAL file), extracts the SQL statements and executes them in the same order and with the original timing against a PostgreSQL database.

If the execution of statements gets behind schedule, warning messages are issued that indicate that the server cannot handle the load in a timely fashion.

A final report gives you a useful statistical analysis of your workload and its execution.

The idea is to replay a real-world database workload as exactly as possible.

This is useful for performance tests, particularly in the following situations:

• You want to compare the performance of your PostgreSQL application on different hardware or different operating systems.
• You want to upgrade your database and want to make sure that the new database version does not suffer from performance regressions that affect you.

To fix this problem, we can install more using the command below.

sudo apt-get -y install pgreplay

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install pgreplay.

sudo apt -y install pgreplay

Or if you have aptitude installed you can use the following command.

sudo aptitude install pgreplay
