I have a DB where this:
 
select 1 into temporary table x;
runs quickly, but
 
drop table x;
 
takes many seconds to run.
 
I don't know why.
 
But:
 
begin;
select 1 into temporary table x;
abort;
 
is very quick.
 
Note the slow dropping applies to automatic dropping of temporary tables when the connection is closed.
I now "abort" all my query sessions for speed.
 
I cannot reproduce this on "template1" and it has not always been the case for my DB.
