I'm don't know what's wrong, but I also don't understand your process.
PDAL will create the appropriate schema for you when it writes the data.
Is there some reason that you're trying to write the schema by hand?  Do
you get different behavior if you simply run the pipeline into an empty
database (use a different pcid)?
