Module dbshell 

manage dbshell — spawn psql / mysql / sqlite3 for the current DATABASE_URL. manage dbshell: open the native CLI client for the current DATABASE_URL.

The URL scheme picks the client, and the process is replaced with exec() on Unix so Ctrl-C reaches the child.

The client itself must already be installed: psql for PostgreSQL, mysql for MySQL and MariaDB, sqlite3 for SQLite. If it is not on PATH, the verb says so.

Enums

DbTarget

What the parser found in DATABASE_URL, split into the parts each client needs.

Functions

command_for

Build the call for target as (program, args, env_vars).

parse_target

Parse a DATABASE_URL into a DbTarget.

run

Start the right CLI for url and hand the process over to it. On success this never returns. Unix uses exec(); other targets run the child and pass its exit code on.
