Comment (by robe):

 Just to confirm it's not something special about this dataset, I created a
 dummy example attached:

 {{{
 \i ticket_transform_issue.sql
 }}}

 outputs


 {{{


    funcname    | calls | total_time
 ---------------+-------+------------
  st_transform  | 11090 |      5.841
  st_intersects | 11084 |     14.881
 (2 rows)
 }}}
