I would not have expected SET STORAGE PLAIN to disable the use of short varlena headers. *Maybe* at some point in time there was enough code that couldn't operate directly on short varlenas to justify a theory that in some circumstances eschewing short headers would save on CPU cycles. But surely in 2021 this is not true and this behavior is not plausibly desired by anyone. -- Robert Haas EDB: http://www.enterprisedb.com
