`currentSchema` support

[vitaly-t]

Introduced in PostgreSQL 9.4, it allows the following syntax:

postgres://username:password@host:port/database?currentSchema=myschema

which needs to be added.

Looks like querystring parsing only supports certain limited number of options. There are a lot more of them: https://www.postgresql.org/docs/9.5/static/libpq-connect.html#LIBPQ-CONNSTRING.

Perhaps we should pass in everything we parsed, and not a subset.

Should be solved with #7.

With typescript :D

import { parse, ConnectionOptions } from 'pg-connection-string';

interface customConnectionOptions extends ConnectionOptions {
  schema: string;
}

const db = parse(process.env.DATABASE_URL) as customConnectionOptions;

console.log(db)
