Yes. OOo files are stored as large objects inside PostgreSQL.

They seems to get truncated.

Only some of them. There is no clear pattern on why this is happening.

Can you explain me what you mean?

This is a production system, where we have a large number of users of
a critical application.

We have experienced bugs in pratically every piece of software we have
used. We are using a policy of "upgrade only if needed, and only after
you are sure that nothing is going to break".

We are definitively going to upgrade to 7.4.17. For the moment, we are
not considering more recent versions.
