Gostgres

Postgres in Go as a learning exercise.

Try me out

Simply run go build ./cmd/repl && ./repl to drop into a psql-like shell where you can issue SQL commands to an in-memory database.

This shell starts with an empty tablespace, but a sample database based on pagila can be loaded via load sample.

$ go build ./cmd/repl && ./repl
gostgres ❯ load sample
gostgres ❯ SELECT f.title, f.rating, c.name
gostgres ❯ FROM film f
gostgres ❯ JOIN film_category fc ON fc.film_id = f.film_id
gostgres ❯ JOIN category c ON c.category_id = fc.category_id
gostgres ❯ WHERE rating = 'R'
gostgres ❯ ORDER BY f.title
gostgres ❯ LIMIT 20;
