Re: New Copy Formats - avro/orc/parquet

Hello

I d'found useful to be able to import/export from postgres to those modern data
formats:
- avro (c writer=https://avro.apache.org/docs/1.8.2/api/c/index.html)
- parquet (c++ writer=https://github.com/apache/parquet-cpp)
- orc (all writers=https://github.com/apache/orc)

Something like :
COPY table TO STDOUT ORC;

Would be lovely.

This would greatly enhance how postgres integrates in big-data ecosystem.
