Postgres Toolkit is a collection of scripts and utilities that allows database administrators to perform complicated PostgreSQL management tasks with single commands. It focuses on frequent tasks like monitoring performance, checking configuration, and managing backups. The open source toolkit currently contains 13 scripts that work on Linux systems and PostgreSQL versions 9.0 through 9.4. It can be installed with a single curl command and includes utilities like pt-config to manage configuration files and pt-session-profiler to monitor long-running queries.
