\copy is not working

[dpxcc]

What feature are you requesting?

\copy hits_moon FROM 'hits.tsv';
ERROR:  columnstore_slot_callbacks not implemented
CONTEXT:  COPY hits_moon, line 0

Why are you requesting this feature?

\copy is useful to load data from client-side

What is your proposed implementation for this feature?

Currently, \copy invokes COPY ... FROM STDIN which DuckDB doesn't support
Prob execute \copy by first uploading the file from client to server, then run regular COPY
