Re: DROP DATABASE is interruptible

I noticed that this patch set introduced this pg_dump test:

But the key "not_like" isn't used for anything by that test suite. 
Maybe "unlike" was meant?  But even then it would be useless because the 
"like" key is empty, so there is nothing that "unlike" can subtract 
from.  Was there something expected from the mention of 
"pg_dumpall_dbprivs"?

Perhaps it would be better to write out

     like => {},

explicitly, with a comment, like some other tests are doing.
