- type Array = (Vector ArrayDimension, Vector Content, Bool, OID)
- type ArrayDimension = (Word32, Word32)
- type Content = Maybe ByteString
- type OID = Word32
- type Composite = Vector (OID, Content)

- type Numeric = (Int16, Word16, Vector Int16)
Documentation
type Array = (Vector ArrayDimension, Vector Content, Bool, OID) Source
A representation of a data serializable to the PostgreSQL array binary format.
Consists of a vector of dimensions, a vector of encoded elements, a flag specifying, whether it contains any nulls, and an oid.
type ArrayDimension = (Word32, Word32) Source
A width and a lower bound.
Currently the lower bound is only allowed to have a value of 1.
type Content = Maybe ByteString Source
An encoded value. Nothing if it represents a NULL.
type Composite = Vector (OID, Content) Source
A representation of a composite Postgres data (Record or Row).
type HStore = Vector (ByteString, Content) Source
HStore.
