Personally I'm more interested in the string being comprehensible to end users than in whether there's any formal rule guaranteeing uniqueness. I really doubt that we will have any practical problem with collisions, so I'd rather go with something like "EnterpriseDB v1.2.3" than with something like "tag:enterprisedb.com,2021:1.2.3". Conceivably we could have two strings, or a printable string and a chosen-at-random unique number (the latter not meant to be shown to users). Not sure it's worth the trouble though. regards, tom lane
