DataError: invalid input syntax for type inet

[AlexxxH]

Request headers from some services, e.g. Google Cloud, include a list of IP addresses in the REMOTE_ADDR field. When the log information is saved to the logging table an error occurs as the format of the IP field does not match type inet in the database table. This causes an error and the information is not saved.

I've made a pull request with a proposed fix: #55
#55

Traceback below, with IP addresses blanked out:

Traceback (most recent call last):

The above exception (invalid input syntax for type inet: "xx.xx.xx.xx, yyy.yyy.yyy.yy"
LINE 1: ...DataView', 'get', 'xx.xx.xx....

) was the direct cause of the following exception:
