Identities should be printed in hexadecimal in SQL

[joshua-spacetime]

If you have a table like this:

pub struct MyTable {
  id: Identity
}

If you do a SQL query on this, the table will be printed like:

id 
----------------------------------------------------------------------------------------------------------------------------------------------------
[143, 144, 204, 148, 169, 150, 141, 246, 210, 151, 186, 166, 101, 3, 168, 147, 177, 195, 75, 11, 0, 38, 138, 81, 72, 152, 221, 149, 75, 13, 162, 11]
[143, 144, 204, 148, 169, 150, 141, 246, 210, 151, 186, 166, 101, 3, 168, 147, 177, 195, 75, 11, 0, 38, 138, 81, 72, 152, 221, 149, 75, 13, 162, 11]
[143, 144, 204, 148, 169, 150, 141, 246, 210, 151, 186, 166, 101, 3, 168, 147, 177, 195, 75, 11, 0, 38, 138, 81, 72, 152, 221, 149, 75, 13, 162, 11]

We just want these to be printed in hex (or maybe base64?) instead of as a byte array.
