It's difficult to see how you could get this error unless there is at
least one backend connected to the target database. Check for
background processes you've forgotten about, etc etc.

What does "\d forum" show as the column name?
If you created the table along the lines of
create table forum ("FID" int, ...);
then all subsequent references to that column name will have to be
double-quoted as well. Unquoted names are implicitly folded to lower
case ... quoted ones are not.
