Robert Schulze	72b9d75a84	Add compat setting for non-const timezones ... SQL function toTimezone() converts a Date or DateTime into another timezone. The problem is that the timezone is part of the Date / DateTime type but not part of the internal representation (value). This led to the fact that toTimeZone() wqith non-const timezones produced wrong and misleading results until #48471 (shipped with v23.4) enforced a const timezone. Unfortunately, this PR also broke existing table definitions with non-const timezones, e.g. in ALIAS expressions. So while #48471 addressed the issue appropriately, it is really backwards-incompatible. This PR adds a setting to toggle the behavior and makes it also part of the compatibility profile.	2023-06-10 16:56:42 +00:00
