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
