The following documentation comment has been logged on the website:

Description:
Section 4.2.3. Subscripts of the documentation states:
> Each subscript is itself an expression, which must yield an integer
value.
However, the following query works on Postgres 12.1
SELECT (ARRAY[1, 2, 3]::integer[])[1.5];
array
-------
2
I believe a more appropriate statement would acknowledge that at least some
values undergo an explicit-style conversion to an integer.
