can't handle same headers in different order

$ cat a.csv
city,state

$ cat b.csv
state,city

$ catcsv a.csv b.csv

Error: error reading 'b.csv
Caused by: CSV headers are different from the first file's

Yes, this is definitely not supported at the moment, by design. If this comes up on a regular basis, we could definitely add a mode where we:

1. Parse the second and later CSVs if the columns don't match the first.
2. Shuffle the columns around.
3. Re-serialize the CSVs.

This might also find its way into dbcrossbar at some point, which will eventually need a mode where it parses the CSV file and manipulates it while piping it through.
