Hi,
I think we need to do something with having two patches aiming to add
global temporary tables:
[1] https://commitfest.postgresql.org/26/2349/
[2] https://commitfest.postgresql.org/26/2233/
As a reviewer I have no idea which of the threads to look at - certainly
not without reading both threads, which I doubt anyone will really do.
The reviews and discussions are somewhat intermixed between those two
threads, which makes it even more confusing.
I think we should agree on a minimal patch combining the necessary/good
bits from the various patches, and terminate one of the threads (i.e.
mark it as rejected or RWF). And we need to do that now, otherwise
there's about 0% chance of getting this into v13.
In general, I agree with the sentiment Rober expressed in [1] - the
patch needs to be as small as possible, not adding "nice to have"
features (like support for parallel queries - I very much doubt just
using shared instead of local buffers is enough to make it work.)
regards
