I have a psql function that make a general sql query, returns a set of

Q.  Is there anyway that I can limit the size of the result sets ?

Put a LIMIT on the query.

If that is not what you want then we will need to see the code and/or get a more detailed explanation of where you want the limiting to occur.
I tried that Limit applies to the total number of results from a query, what I want to do is limit the total number of returns per result set,

For example  if my query returns a set of items such as   id, foo,bar

Normally the result set is 3 set of records one with 3 entries, one with 2 entires and one with entry, the results would be.

1 xx,yy
2 xx,yy
3 xx,yy

1,dd,zz
2,dd,zz

1, ee,ff

If I am only interested in get 2 entries per result set, I would expect to see

1 xx,yy
2 xx,yy


1,dd,zz
2,dd,zz

1, ee,ff

Using LIMIT only gives
1 xx,yy
2 xx,yy

Sorry for not explaining it very, I want to limit the size of an inviduail set of records which is part of set of records.
