Added CREATE TABLE ... EMPTY AS SELECT Query to Deduce Table Structure

Why it matters

This feature allows users to efficiently create tables with schemas inferred from existing queries, eliminating the need to manually define the table structure. It is useful when you want to prepare an empty table matching the result set of a SELECT query for later data insertion.

How to use it

Use the CREATE TABLE ... EMPTY AS SELECT syntax, where the table schema will be deduced from the SELECT query provided, but the table will be created empty without any data inserted.
