Exception in PGConnection

[KingDuckZ]

As per the title, initialization always fails with the following backtrace:

I'm not sure what's going wrong on my system, running the queries from postgres.d line 1723 and 1739 in psql I get a list of non-null positive integer pairs. I'm new to D so I'm not sure how to fix this problem. I'm running a 64-bit gentoo system.

Also, please fix the warning on line 1366. Doing as the compiler says fixes the warning for me:

error: std.algorithm.indexOf!("a == b", string, char).indexOf at /opt/gdc/include/d/4.8.2/std/algorithm.d:4828 conflicts with std.string.indexOf!char.indexOf at /opt/gdc/include/d/4.8.2/std/string.d:252
libs/ddb/ddb/postgres.d:1366: warning: function std.algorithm.indexOf!("a == b", string, char).indexOf is deprecated - Please use std.algorithm.countUntil instead.

PR #24 solves the "Also, please fix the warning on line 1366" part of this issue, by explicitly identifying that the compiler should use std.string.indexOf. It does not use std.algorithm.countUntil because we know this string will not contain any non-ASCII Unicode characters.
