I have also the storage and network transfers overhead in mind:
All those new formats are compressed; this is not true for current

the binary format is 10 to 30% larger than the text one. On the
contrary, an ORC file can be up to 10 times smaller than a text base
format.
That seems largely irrelevant when arguing about using PROGRAM though,
right?
Indeed those storage and network transfers are only considered versus
CSV/BINARY format. No link with PROGRAM aspect.
Just wondering what your time frame is on this? Asking because this
would be considered a new feature and so would need to be added to a
major release of Postgres. Currently work is going on for Postgres
version 11 to be released(just a guess) late Fall 2018/early Winter
2019. The CommitFest(https://commitfest.postgresql.org/) for this
release is currently approximately 3/4 of the way through. Not sure that
new code could make it in at this point. This means it would be bumped
to version 12 for 2019/2020.
