Is it ok to override the updates

1

I am using this code to save the yjs update into PostgreSQL:

const pgPut = async (
  db: pg.Pool,
  key: Map<string, string>,
  val: Uint8Array,
  source: string,
  keys: any[]
) => {
  try {
    const query = `INSERT INTO tex_sync (key, value, plain_value, version, content_type, doc_name, clock, source) 
      VALUES ($1, $2, $3, $4, $5, $6, $7, $8) `;
    const decoder = new TextDecoder("utf-8");
    let text: string = decoder.decode(val);
    let version = key.get("version") || "default";
    let contentType = key.get("contentType") || "default";
    let docName = key.get("docName") ? key.get("docName") : "default";
    let clock = key.get("clock") ? key.get("clock") : -1;
    // https://stackoverflow.com/questions/1347646/postgres-error-on-insert-error-invalid-byte-sequence-for-encoding-utf8-0x0
    let replacedText = text
      .replaceAll("", "")
      .replaceAll("0x00", "")
      .replaceAll(/\u0000/g, "");
    const values = [
      JSON.stringify(keys),
      Buffer.from(val),
      replacedText,
      version,
      contentType,
      docName,
      clock,
      source,
    ];
    const res: pg.QueryResult<any> = await db.query(query, values);
  } catch (err: any) {
    logger.error(
      "Insert tex sync record error:" + JSON.stringify(keys) + ",val:" + val,
      err.stack
    );
  }
};

I added uniq key constains for the key. Now I found the uniq key will conflict. Seems a massive update request arrived in the same time that query the postgresql get the same clock, is it ok to override the content when conflict happen?
