Hi all,
I have a little problem,
I would like to execute
select * from table
and i would like to retrieve the number of records without make
select count(*) from table
I could use directly the table instead of select, and in this this
case I'm searching for
something like the reltuples field in the pg_class table, but I need
this value in real time.
Any suggestion?
Enrico
