Tools for interfacing with Postgres catalog tables

Cat Tools

These are tools that make it easier to interface with the Postgres catalog tables/views/functions. They are meant for use by code, not by people.

To make use of them, you need to grant cat_tools__usage to any roles that need access.

Current Status

This is very much a work in progress. If it doesn’t do something you need, please open an issue!

Supported Versions

Works on Postgres 9.3 and above.
