title: pg-promise - Error operator does not exist: bigint = bigint[]
body: <p>I am trying to run the query:</p>
  
  <pre><code>let query =
      `
          DELETE FROM
              ${table_name}
          WHERE
              _id IN ($1::bigint[])
              AND
              account_id = $2
      `
  let fields =
      [
          _ids,
          account_id,
      ]
  </code></pre>
  
  <p>but it's giving me the error:</p>
  
  <pre><code>operator does not exist: bigint = bigint[]
  </code></pre>
  
  <p><code>_ids</code> is an array.</p>
  
  <h1>NOTE</h1>
  
  <p>The error I was getting once implementing the answer was:</p>
  
  <pre><code>GraphQLError: Int cannot represent non-integer value: []
  </code></pre>
  
  <p>This was simply a GraphQL error, nothing to do with postgres.</p>
