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
