Using the table.field in single-quotes makes it a string, and that is a
strange query.
Legally, you can do:
select count(*) where table.fieldname='something';
select count(table.fieldname) where table.fieldname='something';
However, I see your point, and will add it to the TODO list:
* SELECT COUNT('asdf') FROM pg_class WHERE oid=12 crashes
