SQL Server 2012 :: Open Query To PostGres Passing Parameters?

Looking to pass in the @targetDbName into the Open Query.

The target DB is PostGres and requires 2 single quotes around the dataset name.

I have tried many possible variations using the '+ @variableName +'

USE JonathanDB
declare @dqzDateVer int;
declare @targetDbName varchar(25);
select @targetDbName = DB_NAME();
select @dqzDateVer = dqz_date_ver FROM OPENQUERY(ofr_meta_db, 'select dqz_date_ver from ofr_registry.dataset_feed_state where dataset_name=''JonathanDB'' and state = ''Done'' order by row_iddesc limit 1');
print @dqzDateVer ;
print @targetDbName;
