Functions for dealing with a PostgresSQL connection string
`parse` method taken from [node-postgres](https://github.com/brianc/node-postgres.git)

## Usage
```js
var parse = require('pg-connection-string').parse;
var config = parse('postgres://someuser:somepassword@somehost:381/somedatabase')
```
The resulting config contains a subset of the following properties:
* `host` - Postgres server hostname or, for UNIX domain sockets, the socket filename
* `port` - port on which to connect
* `user` - User with which to authenticate to the server
* `password` - Corresponding password
* `database` - Database name within the server
* `client_encoding` - string encoding the client will use
* `ssl`, either a boolean or an object with properties
* `rejectUnauthorized`
* `cert`
* `key`
* `ca`
* any other query parameters (for example, `application_name`) are preserved intact.
## Connection Strings
The short summary of acceptable URLs is:
* `socket:<path>?<query>` - UNIX domain socket
* `postgres://<user>:<password>@<host>:<port>/<database>?<query>` - TCP connection
But see below for more details.
### UNIX Domain Sockets
When user and password are not given, the socket path follows `socket:`, as in `socket:/var/run/pgsql`.
This form can be shortened to just a path: `/var/run/pgsql`.
When user and password are given, they are included in the typical URL positions, with an empty `host`, as in `socket://user:pass@/var/run/pgsql`.
Query parameters follow a `?` character, including the following special query parameters:
* `db=<database>` - sets the database name (urlencoded)
* `encoding=<encoding>` - sets the `client_encoding` property
### TCP Connections
TCP connections to the Postgres server are indicated with `pg:` or `postgres:` schemes (in fact, any scheme but `socket:` is accepted).
If username and password are included, they should be urlencoded.
The database name, however, should *not* be urlencoded.
Query parameters follow a `?` character, including the following special query parameters:
* `host=<host>` - sets `host` property, overriding the URL's host
* `encoding=<encoding>` - sets the `client_encoding` property
* `ssl=1`, `ssl=true`, `ssl=0`, `ssl=false` - sets `ssl` to true or false, accordingly
* `sslmode=<sslmode>`
* `sslmode=disable` - sets `ssl` to false
* `sslmode=no-verify` - sets `ssl` to `{ rejectUnauthorized: false }`
* `sslmode=prefer`, `sslmode=require`, `sslmode=verify-ca`, `sslmode=verify-full` - sets `ssl` to true
* `sslcert=<filename>` - reads data from the given file and includes the result as `ssl.cert`
* `sslkey=<filename>` - reads data from the given file and includes the result as `ssl.key`
* `sslrootcert=<filename>` - reads data from the given file and includes the result as `ssl.ca`
A bare relative URL, such as `salesdata`, will indicate a database name while leaving other properties empty.
