the use of those functions within triggers or views.

81506b88b8 One of two options on how to address ticket [61c853857f40da49]. In this 
mode, we back out the documentation change of
[https://www.sqlite.org/docsrc/info/07b7749da88d54e5|[07b7749da88d54e5]]
and change the core to work as it has been documented to work since 2017,
rather than how it has actually worked since 2009.

3e4f6c43b8 A minor variation on check-in [1685610ef8e0dc] which (hopefully) makes the 
logic a little easier to follow.  Also disallows the use of the double-quoted
string hack in the query expression used for VACUUM INTO, which is not
strictly required, but moves us toward the goal of disallowing the double-quoted
string hack everywhere.
