gocmdpev

A command-line GO Postgres query visualizer, heavily inspired by the excellent (web-based) pev

Usage

go get github.com/simon-engledew/gocmdpev

Generate a query plan with all the trimmings by prefixing your query with:

EXPLAIN (ANALYZE, COSTS, VERBOSE, BUFFERS, FORMAT JSON)

Then pipe the resulting query plan into gocmdpev.

On MacOS you can just grab a query on your clipboard and run this one-liner:

pbpaste | sed 's/^/EXPLAIN (ANALYZE, COSTS, VERBOSE, BUFFERS, FORMAT JSON) /' | psql -qAt <DATABASE> | gocmdpev

Python 3 Bindings

Build:

go build -buildmode=c-shared -o pycmdpev.so pybindings/*

import pycmdpev

pycmdpev.visualize("<JSON EXPLAIN STRING>")
