And have you read anything about the drawbacks of columnar? They are
there, but writing about them does not makes the headlines.

An option may be good ( may, not sure because nothing is free. More
complex code, more bug surface, some time will be eaten managing the
extra complexity, less developer time available for each feature, ...
) , but IMHO a complete move would be bad. Columnar is not that good
for a lot of postgres usages. If columnar were the silver bullet
everybody would be doing it.
