I doubt that static analysis can help with this problem.
This seems to me

If you don't understand the *specific* C code in question, you're
unlikely to successfully diagnose a problem with the C code.

I wrote this code. It's safe.
In general, it's not possible to split a page without it being
initialized
Hi,
The var OffsetNumber maxoff it's like uint16, see at include/storage/off.h

Within the function _bt_afternewitemoff, at line 641, maxoff is used in an
dangerous expression,
without protection.: (maxoff - 1)
The function: PageGetMaxOffsetNumber that initializes ma
