PQconndefaults should return an array

[pfumagalli]

The PQconndefaults function actually seems to be returning an array of PQconninfoOption structures.

As far as I can see, here, the code only considers the first element in the array, ignoring all others

libpq.rs/src/connection/info.rs

Line 105 in 2cc3094

let raw = pq_sys::PQconndefaults();

As far as I can understand, it should return something similar to PQconninfoPars like here

libpq.rs/src/connection/info.rs

Line 28 in 2cc3094

pub fn from(dsn: &str) -> crate::errors::Result<Vec<Self>> {

You right, thank you.

I depreciated the new function in favor of defaults who returns an array.
