I don't really understand the postings I've found on this issue. This has been going on for quite some time, but now that I'm regularly vacuuming this db, I was looking for any info on how to fix this problem...I don't even know enough about it to know what to include in this message. This is the last output of: vacuumdb -f -z -v rt3 vacuumdb: vacuuming of database "rt3" failed: PANIC: right sibling is not next child in "tickets1" server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
