Thank you very much for your support. After setting the "bytea_output" to "escape" and increasing the Java heap size of DBeaver (to 8GB), I can now see the big column (bytea > 500MB). I am still in the testing phase and haven't finished yet, but I wonder if clients with small RAM will be able to select these big columns or if bytea_output=escape will be visible in the application. Could you please explain this to me in more detail?
