Hello, I vacuumed one of my database tables. In vacuum output I saw the following information about unused item pointers: There were 19310 unused item pointers. As I understand It means that my table's file consists 19310 free tuple pointers. After some minutes I run vacuum again. It was quite unexpected for me that number of unused item pointers was increased to 19351. I thought unused item pointers are used in first place when new tuples versions are created but this example makes me think I am wrong. Can someone explain this to me? ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@xxxxxxxxxxxxxx so that your message can get through to the mailing list cleanly
