Default env vars? about postgrator-cli

[perrin4869]

Those environment variables are documented here actually, and aren't used directly by postgrator-cli at all... so I am not sure how to document their usage ><;;
The idea here was to have this library not get in the way of how the underlying clients work, so if the clients support any kind of environment variables, they should be picked up automatically...

Looks like it does:

postgrator-cli/test/postgrator-cli-tests.js

Lines 247 to 253 in 1ba2b07

	tests.push(async () => {
	console.log('\n----- testing using environment variables to run migrations -----');
	process.env.PGHOST = options.host;
	process.env.PGPORT = options.port;
	process.env.PGUSER = options.username;
	process.env.PGPASSWORD = options.password;
	process.env.PGDATABASE = options.database;

Want a docs PR?

Any PR that improves documentation is very welcome!

Ah ok, I see. Maybe just a quick pointer to that part of the pg docs would save others some research. Thank you!
