More of a "don't rock the boat more than absolutely necessary", but knowing that adding another global struct might be welcomed is good to know.
 

After some research, GetVariable is called by psql_get_variable, which is one of the callback functions passed to psql_scan_create(). So passing a state variable around probably isn't going to work and PsqlFileState now looks like the best option.
