36.7. Field Types

PostgreSQL has a large number of field types, all of which are supported by Webmin. Not all of them are particularly useful for the average database, however. Those that are commonly used are listed in Table 36.1.

PostgreSQL has several types for storing geometric objects, such as point, path, box, and circle, and types for network information such as inet, cidr, and macaddr. Fields of all these types can be created and edited using this module, even though they are not documented above.
