> 1. how can i get count of result's rows where i declare cursor ??
Nothing in DECLARE will tell you this: you will have to do a
SELECT COUNT(*) using the same WHERE clause as the DECLARE to figure
this out. You can always set aside a set amount of memory and only FETCH
that many rows each time of course:
FETCH 23 FROM mycursor;
> 2. I sometime select look like for example select 123 as "Foo 3" , 456 as

You can use aliases in the WHERE clause, but you must be careful about it.
Not sure what you are asking here, maybe you could ask again with a
different example?

Functions are run with the same privileges as the user that calls it by default.
You can change this by adding "SECURITY DEFINER" when creating the function:

4. Is possible to bring pg_hba.conf to db, in to pg_* tables ??
I'm sure someone has done this, but I don't have a pointer handy.
