schemas/util.sql: inlinable IMMUTABLE functions: avoid using config params (e.g. `SET search_path TO util`) because these prevent dynamic inlining (i.e. inlining of a function call with variable instead of constant arguments, by substituting the arguments into the function's body). dynamic inlining can speed up function evaluation significantly, because a (slow) call to a user-defined SQL function is avoided.
