hi.
I still go on looking for query time.
I get a question!
 explain is a command that estimate cost of query time ok, but I don't
know how is the time.for example:
       mybase=> explain select * from tabla1;       NOTICE:  QUERY PLAN:
       Seq Scan on tabla1  (cost=0.00..1.06 rows=6 width=4)
       EXPLAIN
       
the cost query time is 1.06?    1.06......seconds or milliseconds 
  thanks friends!
  bye
