Comment (by robe):

 Well union in this case would be much more efficient.  I'm going to switch
 to that, but not sure it solves your problems.  Did you try doing
 st_union?  I think both st_collect and st_union use transfn so might be
 governed by same array limit.  Though since st_union can collapse, maybe
 not.
