"Assuming that there is a table called table1, this command would
retrieve all rows and all columns from table1."

Maybe it's worth adding:

"Assuming that there is a table called table1, this command would
retrieve all rows and all columns (excluding system columns described
at Section 5.4) from table1."

Since this is a basic SQL tutorial, we don't want to get too far down
into the weeds, or people will get confused.  The next sentence would
need some thought, too:

 The select list specification <literal>*</literal> means all columns
that the table expression happens to provide.

Possibly we could add a footnote?

I agree.  Mentioning system columns at all in this place seems like
too much information.

I considered this but it seems like too much detail for the overview
section.
