I am just running select query to fetch the result
Query : select id, content_data, name from table_name
So here content_data is bytea content which is having more than 700 MB. Even if I run this query in any DB client such as Pgadmin, dbeaver etc.. I'm facing the same error. But this query is being called in java as well
So, I don't think java could be the issue as I can able to successfully insert the data. But, only the problem is with fetching the data that too only specific rows which are having huge volume of data.
Thanks,
Sai

Are you using java? There's an upper limit on array size, hence also on
String length. You'll likely need to process the output in chunks.
