Nested spatial functions are not rendered correctly when the nested function contains a statement parameter:

dwithin(geom, srid(:filter, 0), 1) = true

is rendered as

geom.ST_WithinDistance(?.ST_SRID(0), 1) = 1

which leads to a statement parsing error.

The expression should be rendered as

geom.ST_WithinDistance(ST_GeomFromEWKB(?).ST_SRID(0), 1) = 1
