What exactly do you mean? Yes, fillfactor is defined in StdRdOptions struct, which is shared across many access methods. But some of them uses fillfactor, while others don't. For instance, GIN and BRIN don't support fillfactor at all. > and it gives some > (undocumented) convenient on testing even on GiST. Do you keep in the mind some particular use cases? If so, could you please share them. It would let me and others understand what behavior we need to preserve and why. ------ Alexander Korotkov Postgres Professional: http://www.postgrespro.com The Russian Postgres Company
