Agreed. My approach of per transaction choice may be overkill. Actually, I didn't think per-transaction change was
reallynecessary in practice. But I didn't think of any reason to prohibit per transaction change, so I just wanted to
allowflexibility.
I think per database/user change (ALTER DATABASE/USER) can be useful, in cases where applications are migrated from
otherDBMSs to a PostgreSQL instance. That is, database consolidation for easier data analytics and database
management. One database/schema holds data for a PostgreSQL application, and another one stores data for a migrated
application.
Or, should we recommend a separate PostgreSQL instance on a different VM or container, and just introduce the parameter
onlyin postgresql.conf?
