There is a new CAPI.ExecN command special for Postgres operations.
Oscript, the final frontier. We write the year 2021 and the OScript universe is going to expand. The newest member is CAPI.ExecN.
Bulk Postgres operations are slow. There is a new implementation of CAPI.ExecN, which fixes this. But there is no free beer in the universe. This new implementation exposes Postgres SQL weaknesses (throws SQL errors).
As for 21.1, this is an experimental feature. IN 21.2, it will be activated by default.
For all the explorers in the world, this feature has to be actiated manually in 21.1.
