The first delimiter is ~^~ (tilde-carat-tilde)
The last field is itself delimited with just ^ (carat)
I would use text parsing tools to do this myself though various commands in PosegreSQL could be combined to get the
desiredresult. The last 4 numbers (second parse) should probably be stored in a numeric[]
Look at COPY and regexp_matches()
