I found this in the documentation.
The type "char" (note the quotes) is different
from char(1)in that it only uses one byte of
storage. It is internally used in the system
catalogs as a poor-man's enumeration type.
Is this a SQL standard data type? Can I expect this type
to be supported in PostgreSQL 'forever'? I need an enum
type and obviously this works. At the moment I am not
faced with an imminent port but I hate to back myself into
a corner if I do not have to.
