Hi,
> They seem to think there's basically no way to fix this with the current extension APIs. If someone here happens to know a workaround, I'm sure they would be receptive.
To my knowledge TableAM was never designed to build columnar storages.
The main idea was implementing an undo-logged engine and maybe
index-organized tables.
If Hydra developers know how to improve TableAMs in order to make
columnar storage implementation easier / more efficient I'm certain
their input will be welcomed in the pgsql-hackers@ mailing list.
