Thank you for asking several times for a benchmark.
I wrote it now and it is visible: inserting random bytes into bytea is much
slower,
if you use the psycopg2 defaults.

I tested a ByteA column.

This doesn't seem terribly surprising in bytea_output = escape
mode. Probably

I am curious. Why did nobody say:
store blobs in a storage server (like s3) and only store the blob-id in

Some days ago I asked "Where **not** to use PostgreSQL?" on this mailing list.
Now I realized: Nobody talked about Blobs.
I guess most people do not store Blobs in PostgresSQL.
Where do you store Blobs?
(In my case Blobs are PDF/image files with size up to 20 MByte.

Why would you do this?
What alternative would you suggest instead?

I hope the wiki page is still valid.
