Unfortunately, our current translation machinery is unable to know for sure
whether a subquery reference to an outer table 't1' has opened a table cursor,
an index cursor, or both.
For this reason, return a flag from `TableReferences::find_table_by_internal_id()`
that tells the caller whether the table is an outer query reference, and further
commits will have some additional logic to decide which cursor a subquery will
read from when referencing a table from the outer query.
This PR introduces sparse vectors support and jaccard distance
implementation.
Also, this PR restructure the code to have all vector operations in
separate files (they grow pretty quickly as new vector representations
added to the DB).
Closes#3647
I found an application in the open that expects sqlite_version() to
return a specific string (higher than 3.8...).
We had tons of those issues at Scylla, and the lesson was that you tell
your kids not to lie, but when life hits, well... you lie.
We'll add a new function, turso_version, that tells the truth.
Closes#3635
- On each interaction we assume that the value is NULL, so we need to
set it like so for every interaction in the list. So we force to not
emit this NULL as constant;
- Forces a copy so IN expressions works inside an aggregation
expression. Not ideal but it works, we should work more on the query
planner for sure.

Before, we just skipped evaluating `Id`, `Qualified` and
`DoublyQualified` if `referenced_tables` was `None`, leading to shit
like #3621. Let's eagerly return `"No such column"` parse errors in
these cases instead, and punch exceptions for cases where that doesn't
cleanly work

SQLite surprisingly supports this:
select sqlite_version(*);
this gets translated at the parser level to sqlite_version(), and it
works for all functions that take 0 arguments.
Let's be compatible with SQLite and support the same thing.
closes#3282
includes minor refactor, removing `column_is_rowid_alias`, which is only
checking the public field of the argument Column.
