PITR feature was introduced in PostgreSQL 8.0 No help there. You are looking at data loss unfortunately. How complete data loss depends on how relatively intact the structures are and how much time and effort you are willing to spend fixing problems causing errors like the above. * did you recover part or all of the database volume? * were you running with fsync off or on? merlin ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
