what is your use case for doing this? You should not be messing with the files used in your database unless you know what you’re doing

I need to get 2000 PDF files from Google Drive and send them to OpenAi, but my Postgres was full when I started downloading the binary file, I needed to increase my limit. It would be interesting to store them in a temporary file.

Postgres should not be used for object storage. Use a cloud bucket like Amazon S3 https://aws.amazon.com/s3/

so theoretically it's not the binary files that are in postgres. I'll do more tests
