This way i can use the function in the from clause of the query that
i already had to do to get the totals formatted with to_price. In this
case, i believe it is better to leave out Go’s function because it would
force me to perform two queries.
Instead of binding a nullable string pointer with the payment’s slug,
i wanted to use pgtype’s zeronull.Text type, but it can not work in this
case because it encodes the value as a text, while the parameters is
uuid. I can not use zero.UUID, because it is a [16]byte array, while i
have it in a string.
Thus, had to create my own ZeroNullUUID type that use a string as a base
but encodes it as a UUID.
