Querying for name/value pairs in reverse

I'm no SQL expert by any means so I'm wondering if something like this
is possible.

I have two tables like this:

create table Errors (
Id serial not null,
CreateDate timestamp not null,
primary key (Id)
);

create table ErrorValues (
Id serial not null,
ErrorId int not null,
Name varchar(255) not null,
Value text not null,
primary key (Id),
foreign key (ErrorId) references Errors (Id)
);

Now, selecting specific ErrorValues with a bunch of names that are
related to an Error is of course pretty simple. But I want to go the
other way. I want to query for:

'give me all Errors that have the Code=1234 AND Address=1.2.3.4 AND
Type=OSX Name/Value pairs'

What is a good recipe to deal with this? Is something like this
possible with standard sql? Is there a nice PG way to do this?

Are there good books that cover real world stuff like this?

So many questions from a SQL noob.
