Opens a new connection to a PostgreSQL server and resolves to the connection (PgConn) once authenticated and ready to accept queries.

Usage:

const db1 = await connectPg('postgres://username:password@hostname/database', { ... more opts ... });
const db2 = await connectPg({ hostname, username, password, database });
const db3 = await connectPg({ transport: 'unix', path: '/foo/bar.sock', username });

Requirements:

• tcp with ssl (default) requires --allow-net and --unstable
• tcp without ssl requires --allow-net
• unix requires --allow-read and --unstable
