The following documentation comment has been logged on the website:

Description:
In 5.6.1. Adding a Column, there is a kind of example 'ALTER TABLE products
ADD COLUMN description text;'
The words 'description' and 'text' are misleading -- as according to the
formal documentation of the SQL command
(https://www.postgresql.org/docs/12/sql-altertable.html) they should be
'column_name' and 'data_type'.
A similar problem exists for removing a column, and other actions.
