Comment (by Simon Charette):
Nailed it down to [https://www.postgresql.org/docs/release/15.6/ a change
in Postgres 15.6 released on 2024-02-08] so it makes sense that bcail ran
on that only recently against PG 15.
> **Fix function volatility checking for GENERATED and DEFAULT expressions
(Tom Lane)**
>
> These places could fail to detect insertion of a volatile function
default-argument expression, or decide that a polymorphic function is
volatile although it is actually immutable on the datatype of interest.
**This could lead to improperly rejecting or accepting a GENERATED clause,
or to mistakenly applying the constant-default-value optimization in ALTER
TABLE ADD COLUMN**.
