Fixes

• Fixed an issue with the quote_ident scalar function that caused it to quote subscript expressions like "col['x']" instead of "col"['x'].
• Fixed an issue that prevented the use of subscript expressions as conflict target in ON CONFLICT clauses of INSERT statements.
• Fixed an issue where drop snapshot on an azure repository would not delete all the related data.
• Fixed an issue that could lead to a Field is not streamable error message when using window functions.
