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)
}}}
