Sequelize raw query update array of objects as replacements

Question

I am using sequelize (postgres) and I need to properly escape a query like this:

`
       UPDATE "Pets"
       SET "name" = CASE LOWER("name")
         ${input.pets
            .map((pet) => `WHEN '${pet.name.toLowerCase()}' THEN '${pet.newName}'`)
            .join('\n')}
          ELSE "name"
          END
        WHERE LOWER("name") IN(${input.pets
          .map((pet) => `'${pet.name.toLowerCase()}'`)
          .join(',')});
`

Sample input.pets:

[{ name: "rocky", newName: "leo" }]

Does anyone have an idea how to achieve this with replacements?

I have found a thread on github which suggested something like this:

let data = [ [ 252456, 1, 55, '0' ],
[ 357083, 1, 56, '0' ],
[ 316493, 1, 57, '0' ] ];

db.query(
  `INSERT INTO product (a, b) VALUES ${data.map(a => '(?)').join(',')};`,
  {
     replacements: data,
     type: Sequelize.QueryTypes.INSERT
  }
);

However, a 2d array is being used here not an array of objects. Is there a way to access individual properties from the array? When I try something like this

`
       UPDATE "Pets"
       SET "name" = CASE LOWER("name")
         ${input.pets
            .map((_pet) => `WHEN ? THEN ?`)
            .join('\n')}
          ELSE "name"
          END
        WHERE LOWER("name") IN(${input.pets
          .map((_pet) => `?`)
          .join(',')});
`,
    { type: QueryTypes.UPDATE, replacements: input.pets },

The first ? turns out to be the whole object. Is there a way to access it's properties? I also tried transforming input.pets into a 2d array but still couldn't get it to work as in example with insert above.

In advance thanks for your time
