Comment (by komzpa):

 Good news, this form of that line returns instantly for me and will allow
 concave hull to still cover a polygon:
 {{{
 var_resultgeom := public.ST_Union(ST_CollectionExtract(param_inputgeom,
 3), var_resultgeom);
 }}}

 Bad news, it's not returning a concave hull - lines are hanging outside of
 it.
