Description:
https://www.postgresql.org/docs/16/functions-string.html
Said
text ^@ text → boolean
Returns true if the first string starts with the second string (equivalent
to the starts_with() function).
'alphabet' ^@ 'alph' → t
This is not true equivalent, because ^@ can be accelerated by special
SP-GiST index
https://www.postgresql.org/docs/14/spgist-builtin-opclasses.html
while function starts_with() perhaps no.
Thus need to mention in the description of ^@ it can be accelerated by the
special index with link to it. And in the description on start_with() need
to mention that alternative ^@ is better, because it can be accelerated by
index, while the function is not.
