WITH func_call AS ( SELECT function_call(...) AS func_out_col ) SELECT (func_out_col).* FROM func_call; Basically you have to execute the function call and leave the result as a single column (a row type). Then, in another layer of the query, you expand that single column into its components using "*". Because you are expanding a column and not a table you must put the column name in "()" - otherwise the parser thinks "func_out_col" is a table and errors out. This all definitely applies to 9.2 and earlier. 9.3 (with lateral) may behave differently...
