1.8.4 bug DB Restriction field

DB Restriction field borks on datname IN ('blah') or datname='blah' with the error: "ERROR:  operator does not exist:
name<> boolean LINE 5:  WHERE datname NOT IN (datname='blah')
 

Here's the full query from the logs being sent from pgAdmin:
SELECT db.oid, datname, db.dattablespace AS spcoid, spcname, datallowconn, datconfig, datacl,
pg_encoding_to_char(encoding)AS serverencoding, pg_get_userbyid(datdba) AS datowner,has_database_privilege(db.oid,
'CREATE')as cancreate, current_setting('default_tablespace') AS default_tablespace FROM pg_database db LEFT OUTER JOIN
pg_tablespaceta ON db.dattablespace=ta.OID WHERE datname NOT IN (datname='blah')
 

Sincerely,

Zach Conrad
