Well, notice that the keyword in here would be
"utility" -- psql is a program that interacts with
the user, and as such, it can do any processing and
add any logic it wants.

I always thought the semicolon was a psql thing,
which it would use to determine when the user is
done entering the SQL statement.  For libpq or other
client libraries, the way I saw it, it is the end
of the received string what would allow the backend
to figure out where the SQL statement ends.

Thanks,

Carlos
