This Rust tool is a port of the python tool - pageinspect_inspector tool by Louise Grandjonc. It allows you to inspect and analyze the internal structure of PostgreSQL indexes, highlighting page layout and tuples and in my opinion, it's a pretty cool project to work on :D

This tool currently only supports btree indexes. (Support GIN indexes planned later on). It leverages handlebars for visualization of the trees with minor tweaks from original python project.

Sample output of the tool:

1. Install pageinspect extension in your database.
2. Clone the repository and run cargo run --release -- -o <output-path-for-html> -i <index-name> -u <postgres-user>
3. You can run cargo run --release -- --help for more flags.

1. The tool currently only supports btree indexes.
2. This tool's UI could use some bug fixes. (PRs are welcome)
3. With large indexes, the tool might take a while to generate the output (imagine ~1 min), and dynamic rendering of lines might break the UI.
