Inserting an array into a Postgresql database

Question

I want to be able to write an array of bigints into a table that I am using for history in Go. Unfortunately, I can\'t and when I do the error sql: converting Exec argumen

Answer 1

Implement database/sql/driver.Valuer with a custom type:

type int64array []int64

func (a int64array) Value() (driver.Value, error) {
    // Format a in PostgreSQL's array input format {1,2,3} and return it as as string or []byte.
}
