Db.Where("author = &1", "俺やろ").First(&readPost)でエラー

エラー内容

[2023-06-01 22:46:17]  pq: operator does not exist: & integer 
panic: runtime error: index out of range [0] with length 0

問題のコード

実行環境は、PostgreSQL14
プレースホルダーの問題の様でGoでは$1ではなく?で基本的にコーディングすればよい

// 動かない
Db.Where("author = $1", "俺なのか").First(&readPost)

// 動く
Db.Where("author = ?", "俺なのか").First(&readPost)
