I am quite certain that it is also the case for Oracle and MySQL.
I suspect that it is true for all SQL databases, since SQL distinguishes
between data definition (DDL) and data manipulation (DML) statements.
Loading data into a table is data manipulation, and you don't want that
to change your data definition as a side effect.
Which database can automatically create columns while loading a CSV file
into a table?
(It is of course possible to write a program which guesses the types of
the columns from the contents of the CSV file and then issues an
appropriate CREATE TABLE or ALTER TABLE statement. I wrote one 20 years
ago. But that's an application program, not part of the database.)
