You might find a few hints if you use strict; and used -w or use warnings; (depending on your version of Perl).

In your foreach $guest loop your split is not acting on $guest as you have mis-placed your brackets. Because of this, you never find the matching record that you want to change, and so your file is never any different after execution. Warnings would have caught this problem.

    [erix]: I don't know but I think extracting that from Pg is probably not so easy (or it would be done more often, no?)
    [Corion]: erix: There is somebody who has hacked up some Ruby scripts to do just that, but the Ruby scripts have some hardcoded #defines (well, reimplement those), so the extraction doesn't compile for Windows...
    [Corion]: libpg_query
    [Corion]: ... and I think "porting" it basically means (re)implementing a C preprocessor and feeding that one with the appropriate #defines for the platforms, and/or providing stub implementations for OS-specific functions that the query parser really wants to call
    [erix]: ah, interesting. Well, sounds like a good start..
    [Corion]: In the long run, obviously, the parser wouldn't need/call OS-specific stuff anyway, but we're a long way from that :D
