Is it possible to automatically create a table in PostgreSQL from a csv file with headers?

Question

According with the documentation https://www.postgresql.org/docs/current/sql-copy.html , PSQL command COPY cannot create a table from a tsv or csv file. You need to create a table and its columns before you can COPY to it. Is there any workaround for this issue?

There's some ways to workaround this issue.

You can find some scripts around the internet which will do what you're looking for, but the best way I know is using this Data Mover Project.

Besides, it's already published to docker as techindicium/spark-datamover:v0.1. You can call it from the command line:

docker run --network host techindicium/spark-datamover:v0.1 -s /home/path/your_file.csv --filetype csv --destination "jdbc:postgresql://localhost:PORT/DATABASE?user=USERNAME&password=PASSWD" --destination-table MY_DEST_TABLE
