Hello, could you please sign the CLA? Also please notice that tests are failing, probably due to the changes in this PR

[giuliocalzo]

hi @aeneasr I've update the PR, all test are now passing (a part Docker Image Scanners but I believe is not related to my change)

[aeneasr]

Thank you! This looks good to me - quick question - is uuid-ossp supported everywhere? According to the docs it's in Supported Versions: Current (17) / 16 / 15 / 14 / 13

[giuliocalzo]

hi @aeneasr unfortunately is only supported for newer version 13+
do you plan to keep supporting EOL postgresql versions ?

[aeneasr]

No, I think version 12 does not need to be supported.
