I haven't explicitly tested, but there's no reason to expect it's any
different from PostgreSQL's own maximums.

That said, I wouldn't personally use large objects anywhere near the
maximum. The performance won't be great, and it's a pain for backup and
restore.

I've used 300MB objects, no problem. The only limit is java max
memory, the object load uses around 1.5 times the object size, at
least on ASCII transfers, I'm not sure if binary transfers are already
default.

Hi,

it depends. If you access blobs via byte[] (i think) the limit is at 1GB
We use streams with lo module in one project and have some entries with
more than 4GB in access with a java runtime with less than 2GB memory.
Works as expected.

best regards
Thomas
