Bug or feature?

Hi, I can run following odd command(note that no spaces between 1 and
where):

test=# select 1where true;

Is this a bug or a feature? This is PostgreSQL 8.1.0.

Standard flex lexer behavior. "1" followed by "w" cannot begin
a legal token, therefore "1" is a token by itself.

This is not really any different from the fact that you can write
"2+2" without any spaces.
