So, because _width is of type numeric, a line like(st_xmin(_geom) / _width)::INTEGER * _width - (_width * 1.5)will end up being of type numeric. So, you need to cast the whole expression, eg,(st_xmin(_geom) / _width)::INTEGER * _width - (_width * 1.5))::bigint

and have you tried explicit type casts? PG function calls usually don't like type ambiguity much at runtime.

What version of Postgres are you using, the generate_series(numeric,numeric,numeric) function was only added in Postgres 9.5. So, if you have lower, do as @ThingumaBob suggests, and cast to int or bigint.

So, because _width is of type numeric, a line like
(st_xmin(_geom) / _width)::INTEGER * _width - (_width * 1.5)will end up being of type numeric. So, you need to cast the whole expression, eg,(st_xmin(_geom) / _width)::INTEGER * _width - (_width * 1.5))::bigint– John Powell
