Does this mean that substr calls substring internally?? Or is it the

Looks like they're pretty evenly matched.
Actually, a bit of poking into the contents of pg_proc will show you
that they are both aliases for the same C function (text_substr_no_len).
So they should be *exactly* the same speed.

I was looking for Tom's answer).
Thanks Tom for your answer.
