With triggers it is a bit hard to decide. Since people other than the
table owner can create them, but then they effectively belong to the
table owner. I think that makes having them execute as the table
owner reasonable. The table owner is taking his chances by letting
other people create triggers on his table.

For constraints and default expressions I don't see any problems for
having them execute as the table owner. This provides a small advantage
in providing limited update ability for sequences, that would otherwise
require creating a function to achieve.

As long as people realize that when they insert, update or delete from
a table owned by someone else they need to trust that person it probably
isn't a big deal. The descriptions of triggers hint at this but from
a different perspective (that of a table owner letting people create
triggers on his table) and people might not make the connection (assuming
they even read about triggers).
