The index complaint also suggests on-disk corruption --- it means that the btree version information that's stored in the first page of a btree index wasn't right. How exactly did you "shut down the server"? Have you noticed any other evidence of disk problems, outside Postgres? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
