gocmdpev
A command-line GO Postgres query visualizer, heavily inspired by the excellent (web-based) pev
Usage
go get -u github.com/simon-engledew/gocmdpev
or via Homebrew:
brew tap simon-engledew/gocmdpev
brew install 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 '1s/^/EXPLAIN (ANALYZE, COSTS, VERBOSE, BUFFERS, FORMAT JSON) /', psql -qXAt <DATABASE>, gocmdpev
