92+**Enumerated Types**
93+
94+PostgreSQL has a powerful type system. It even allows for user defined types.
95+For instance, you can define enumerated types which are data types that comprise
96+a static, ordered set of values. An example of an enum type might be the days of the week,
97+or a set of status values for a piece of data.
98+
99+Enumerated types are created using the `createTypeEnum` command, for example
100+
101+```Haskell
102+>>> printSQL $ createTypeEnum #mood (label @"sad" :* label @"ok" :* label @"happy" :* Nil)
103+CREATE TYPE "mood" AS ENUM ('sad', 'ok', 'happy');
104+```
105+
106+Enumerated types can also be generated from a Haskell type, for example
107+
108+```Haskell
109+>>> data Schwarma = Beef | Lamb | Chicken deriving GHC.Generic
110+>>> instance SOP.Generic Schwarma
111+>>> instance SOP.HasDatatypeInfo Schwarma
112+>>> printSQL $ createTypeEnumFrom @Schwarma #schwarma
113+CREATE TYPE "schwarma" AS ENUM ('Beef', 'Lamb', 'Chicken');
