Your issue is placing the SRF (set returning function) in the select-list which causes it to be treated as a single composite-typed column. You need to place the function in after "FROM" or "LATERAL" Something like: SELECT * FROM src_tbl LATERAL my_func(src_tbl.col1, src_tbl.col2) I haven't had much experience writing lateral clauses but their benefit is that they can reference columns from other tables so you don't have to place the function in the select-list.
