The example for creating a check constraint is missing a comma
The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/10/static/sql-createtable.html
Description:
See the example from the documentation for CREATE TABLE below. There should
be a comma before the CONSTRAINT keyword.
CREATE TABLE distributors (
did integer,
name varchar(40)
CONSTRAINT con1 CHECK (did > 100 AND name <> '')
);

Hmm ... that example is legal syntax as-is, but considering that the
explanation for it says specifically that it's table-constraint syntax
not column-constraint syntax, I think you're right.

Oh yeah! You're right, strictly speaking it does work. I guess I read it
as a table constraint because it's on the next line.
