Hi, I have a question which does not seem to be covered in the documentation: I have a function f(i) that returns a table with three columns (a, b, c).
In the documentation (http://www.postgresql.org/docs/8.4/interactive/xfunc-sql.html#XFUNC-SQL-FUNCTIONS-RETURNING-SET) it says that (even though deprecated) you can call such functions in a SELECT clause like so: SELECT id, f(id) FROM some_table . This will give me a two column table that looks like this: id | (a, b, c) However since I want a 4 column table like this id | a | b | c , I do this instead: SELECT id, (f(id)).a, (f(id)).b, (f(id)).c FROM some_table. However I'm not quite sure if this really gives me what I want (i.e. the same as in the first query only with the tuple elements as separate columns). Of course I'm open to suggestions on how to do this more elegantly and also how one can do something like this without using the deprecated feature of calling a set returning function in SELECT.
