I would say yes...array_accum is virtually an essential function when
working with arrays and the suggested array_to_set (and it's built in
cousin, _pg_expand_array) really should not be built around
generate_series when a C function is faster and will scale much
better.
array_to_set, as suggested in SQL, is something only a relative expert
with PostgreSQL could be expected to write.
Thus could generate_series be relieved from providing the only core
function for set returning functions in the documentation. IMO, this
part of the documentation could use some expansion anyways :)
