It looks like plain old COPY would do this just fine, along the lines
of (in psql)
\copy myTable(content) from 'myfile.ndjson'
If the newlines actually are \n\r rather than the more usual \r\n,
you might have to clean that up to stop COPY from thinking they
represent two line endings not one.
I'd advise extracting the first hundred or so lines of the file and doing
a test import into a temporary table, just to verify the process.
