It looks like yours is defined that way, so that might be why it’s not being inlined. Hope this helps Philip
Thank You, Philip.
The link you've provided helps a lot explaining why the body of
my SQL function is not inlined.
Any thoughts on why the execution times differ so much? I see
planning of a plain SQL is 0.550ms. So I expect the SQL function
to spend that time planning (inside), but I get 50ms (100 times
longer).
