At the level of bikeshedding ... I quite dislike using the name "popcount"
for these functions.  I'm aware that some C compilers provide primitives
of that name, but I wouldn't expect a SQL programmer to know that;
without that context the name seems pretty random and unintuitive.
Moreover, it invites confusion with SQL's use of "pop" to abbreviate
"population" in the statistical aggregates, such as var_pop().

Perhaps something along the lines of count_ones() or count_set_bits()
would be more apropos.
