sqlpp::optional is an alias for std::optional for C++17 and beyond.
Otherwise, it is a simple and incomplete backport.
For older versions of C++, the library offers simple back
Similar for string_view and span.
Before this change, sqlite3::connection::execute silently
ignores statements after the first one (separated by semicolon).
After this change, trailing statements are detected and an
sqlpp::exception is thrown.
This change also adds documentation to other connectors indicating
that execute is supposed to be used with single statements only,
even though it is possible to do otherwise.

* When closing a transaction do it in the following order: report (if any), execute SQL command, set transaction active flag to false.
MySQL 8.0.34 deprecates `MYSQL_OPT_RECONNECT`. As discussed in #530,
this commit is removing library support for (auto-)reconnect.
It is of course still possible to reconnect directly using the native
handle.
_head used to represent the position of the next push_back()
and _tail used to represent the position of front().
This CL renames them to avoid confusion.

- The postgres connection does not change the connection_config thus passing it as const.
- Implies 'thread safety' when using the same config for multiple connections

* When inserting values into "timestamp with time zone" fields treat the value as being in the UTC time zone.
* Simplify parsing of PostgreSQL date/time responses by using regular expressions. Always convert response times with time zone to UTC.
* Add tests which check if timestamp and date fields are treated as having a UTC time zone.
* Clarify the test comments.
* value: add missing includes
* mysql, sqlite3: use explicitly *out* stringstreams for serialization
* postgresql: fix: use max_digits10 instead of digits10
* detail: add float_safe_ostringstream, ensuring floats are serialized with enough precision
* mysql, postgresql, sqlite3, tests: fix: set float-precision for all streams
* run clang-format on changed files
* inline remove_cvref.h
* replace unspecific "wrapper" with concrete type name
* tests: split connector specific tests out of serialize/Float
Leak: The sqlite3 connection handle destructor was
accidentally turned into a default constructor during the
migration of repositories.
Replaced the sqlite3 raw pointer with a unique_ptr to prevent
this kind of accident.
Removed timezone handling in the process (needs to be documented).
Note: on_conflict does not check for constraints (needs to be documented).
Note: some of the constraints tests seem to be aiming for a different static_assert.
Changed sqlite3 usage tests to be linked into one executable.
This provokes multiple definition errors for non-inlined free
functions.
Also ran clang-format on the changed headers.
The compiler actually does a much better job at telling you if two
result columns have the same name as soon as you are trying to use
them.
In contrast to the static_assert, the compiler will even say which
name is ambiguous.
This was a special feature for a project I was working on long ago.
It provided implicit behavior for trivial value (0 or "") which were
supposed to be interpreted as NULL.
They led to `operator==` potentially being serialized as 'IS NULL'.
It makes more sense to introduce explicit helpers, e.g.
- equal_or_is_null(col, optional)
- not_equal_or_is_not_null(col, optional)
* Minimal over() implementation for aggregate functions
* auto_alias support for over()
* add missing typename
* Test .over() serialization
* Add missing return to test
* Fix testing over auto alias
