There's north of 150 other examples (just grep for '= lfirst' in the
source). Some were even committed by Peter E :-)
In the discussion with Andres the same point came up for palloc, for
which I suggested we add something along the lines of:
#define palloc_object(_type_) (_type_ *) palloc(sizeof(_type_))
#define palloc_array(_type_, n) (_type_ *) palloc((n) * sizeof(_type_))
palloc() without a cast is even more common than lfirst() without one,
and something like half of those (and 80%+ of the pallocs that do have a
cast) are palloc(sizeof(...)) or palloc(something * sizeof(...)).
