This distinction has not basis in SQL syntax.

If it helps, compare this to ECPG: The C parts follow the syntax rules
of C, the SQL parts follow the syntax rules of SQL. In psql, the psql
parts follow the syntax rules of psql, the SQL parts follow the syntax
rules of SQL. The syntax rules of psql in turn are inspired by Unix
shells, sort of because psql is used that way. (Surely one wouldn't
want the argument to \i be case-insensitive?)
