Greetings, I am running Postgresql 8.0 on "Linux xxx 2.4.18-14 #1 Wed Sep 4 12:13:11 EDT 2002 i686 athlon i386 GNU/Linux" and while loading data my program received: DBD::Pg::db do failed: server closed the connection unexpectedly ... Now I can't access any data in the DB, not even the \d command: mydb=# \d ERROR: could not identify an ordering operator for type name HINT: Use an explicit ordering operator or modify the query. I tried vacuum: mydb=# vacuum; ERROR: could not open relation 1663/12649295/16396: No such file or directory What would be the best way to fix this? How would I determine what caused the corruption and prevent it from happening again? Thanks for any assistance, Drew.
