The GNATColl code did so.

This is nonsense. Ada has exactly the same requirement.
In Ada, you cannot write
     Ada.Text_IO.Put_Line (Hello, world!);
you must write
     Ada.Text_IO.Put_Line ("Hello, world!");

SQL is a type of programming language, and SQL statements that
involve literal strings must have them be quoted. Programmers
sometimes construct SQL statements dynamically and interpolate
data as string literals into the SQL, and then those must be
properly quoted. But SQL interfaces also grant the ability to
build SQL statements with placeholder parameters where values
for those parameters are passed separately when the statements
are executed, and in that case the parameters are simply passed
as-is with no quoting required.

But Ada has the same idiocy:
<http://www.adaic.org/resources/add_content/standards/05rm/html/RM-2-6.html>
     string_literal ::= "{string_element}"
     string_element ::= "" | non_quotation_mark_graphic_character

No, because GNATColl provided an interface to Ada programmers.
That interface was free to use any Ada design methodology and
type design that its creators wished to use, regardless of the
requirements of the Postgres programming interface.
