I have the following function:

RETURN QUERY
select n.UserId, u.Alias, n.Date, n.Data
--Bunch of joins, etc
If I understand correctly, I have to return "SETOF record" since my result set doesn't match a table and isn't a single value. However, this means when I want to call it I have to provide a column definition list, such as:
select * from foo as (...);
Is there any way to specify this column list within the function itself? The problem I'm running into is I want to call this function using Npgsql which doesn't appear to support passing in a column definition list.
One idea is to use a view and then have the function select * from the view and apply the where clause. However, I'm not sure if this would be as performant since views may not be indexed (dunno if this is true or not)..
Any other ideas would be appreciated.. Thanks!
