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. regards, tom lane
