Interesting:
test=> select case when true then t.c end from t;
case
-------
54.36
(1 row)
test=> create function f(t) returns m as $$ select case when true then
$1.c end $$ language sql;
ERROR: return type mismatch in function declared to return m
DETAIL: Actual return type is numeric.
CONTEXT: SQL function "f"
test=> create function f(t) returns numeric as $$ select case when true
then $1.c end $$ language sql;
CREATE FUNCTION
test=> select f(t);
ERROR: column "t" does not exist
LINE 1: select f(t);
I will admit I am at a loss. Maybe someone else can illuminate.
