FYI: I'm proposing making COPY format extendable:
* https://www.postgresql.org/message-id/flat/20231204.153548.2126325458835528809.kou@clear-code.com
* https://commitfest.postgresql.org/48/4681/
If it's accepted, we can implement extensions for COPY
FORMAT arrow and COPY FORMAT parquet. With these extensions,
we can use file_fdw to read Apache Arrow and Apache Parquet
file because file_fdw is based on COPY FROM:
https://www.postgresql.org/docs/current/file-fdw.html
If you're interested in this proposal, you can review the
latest proposed patch set to proceed this proposal.

The above COPY support will help this.
