Well, considering id is your primary key and therefore very probably
unique, you could as well do: select ser, 1 from tab1 where id=$1;

Otherwise, whatever interface you're using is likely to have a rowcount
value for you.
If that's not what you're looking for, please don't make us guess what
you want to achieve.

Your question might be unclear.
I might be wrong but is it a PG/pgSQL funtion you are writing?

In that case i think you can use:

select into val1,val2 ser,count(*) from tab1 where id = $1;

(found in chapter "37.6.2 Select into" in my 7.4.2 documentation:
