I think changeable regex flavors turned out to be a bad idea. They can

your application fails to work as expected. Maybe we should make that
setting PGC_POSTMASTER (or just get rid of it?), and provide was to pass
flags to change the flavor for particular operations (this is easy for
function-based stuff but not so easy for operators). That way it
doesn't intrude in stuff like cached plans and so on.
Maybe so. I think it was originally intended mostly as a
backwards-compatibility measure when we added the support for ARE
flavor. It's pretty likely that no one changes the flavor setting
in practice anymore. If we just locked it down as "advanced always"
then we could simplify the documentation by a measurable amount ...
yeah I don't recall a single incident in the last few years that
required playing with the regex flavours....
