of course. You can always explicitly open a transaction on the remote
side over dblink, do work, and commit it at the last possible moment.
Your transactions aren't perfectly synchronized...if you crash in the
precise moment between committing the remote and the local you can get
in trouble. The chances of this are extremely remote though.
