What version of PostgreSQL?  What's the exact error message?  That
often provides a clue as to what's wrong.  I'll guess that the
Windows box is running 8.1.x and the error is:

ERROR:  missing FROM-clause entry for table "pg_class"

Why don't you want to rewrite the query?

Another guess: the Linux box is running a version of PostgreSQL
older than 8.1, or if it's running 8.1 then you've enabled
add_missing_from.  As the 8.1 Release Notes mention, that option
is now disabled by default.  Rather than trying to make the query
work as-is, rewrite it to be proper SQL by adding pg_class to the
FROM clause.
