Querying Postgres composite types from golang - postgresql

Question

So I am using go-gorp to query postgres and I can't seem to query the composite type inside my table is giving an error. All I want is appropriately nested JSON response. My postgres schema is:
CREATE TYPE PhoneType AS ENUM ('MOBILE', 'HOME', 'WORK');
CREATE TYPE PhoneNumber AS (
"Number" VARCHAR,
"Type" PhoneType
);
CREATE TABLE Person (
"Id" SERIAL PRIMARY KEY NOT NULL,
"Name" VARCHAR NOT NULL,
"Email" VARCHAR,
"Number" PhoneNumber[]
);
Correspondingly in golang, I have
const (
MOBILE PhoneType = iota
HOME
WORK
)
type PhoneNumber struct {
Number string
Type PhoneType
}
type Person struct {
Id int
Name string
Email string
PhoneNumber // not sure how to get array of phone numbers here
}
And to query, I am using go-gorp as follows:
dbmap := &gorp.DbMap{Db: db, Dialect: gorp.PostgresDialect{}}
var data []Person
_, err := dbmap.Select(&data, "SELECT * FROM Person")
the result I get has the format
{
"Id":
"Name":
"Email"
"Number": "{\"(..., ...)\"}"
"Type": 0
}
what I'm expecting is:
{
"Id":
"Name":
"Email":
"PhoneNumber": [{
"Number":
"Type":
}]
}
How can I change this nested composite type to the type friendly to my declaration in go?
EDIT: Looks like postres arrays and composite types become strings in go. How can I redesign the schema to achieve similar result?

Answer 1

your type declaration is wrong, try this for example:
type Phone struct {
Number string
Type PhoneType
}
type Person struct {
Id int
Name string
Email string
PhoneNumber []Phone
}
