Struct OutCol 

pub struct OutCol {
    pub key: String,
    pub name: String,
}

One output column: the key it is stored under, and the name the client sees.

These are NOT always the same, and that is the whole point. PostgreSQL permits duplicate output names — SELECT e.name, e2.name legitimately returns two columns both called name, and generated SQL relies on it. Rows here are JSON objects, so two columns sharing a key would share a VALUE: the second write silently overwrote the first, and the query above returned the same value twice while reporting two columns.

So the key is made unique and the display name is left alone. Renaming the column instead would be worse — generated SQL asks for the name it wrote.
