I might be colorblind from $dayjob, but I don’t think that these installations (data warehouses et.al) are that uncommon. They are also installations that risk staying on an old version due to upgrades being non-trivial (not saying that in-place is trivial, just that there are places where it may make sense). > I have the feeling that in-place > binary upgrades are going to end up sapping developer time Having worked on supporting the 8.2->8.3 on-disk format change in pg_upgrade for GPDB, I am not arguing against that. Not at all. cheers ./daniel
