other database?  is that on the same postgresql cluster?   or on a 
seperate instance of the postgres server on the same VM?  or on a 
seperate VM on the same host ?

what does `iostat -x 5` show ?   let it run a bunch of samples, then run 
this slow query and get more samples.   pay attention to the disk 
drive(s) the database is stored on.

high %utilization or await times would be a bad thing.
