The following review has been posted through the commitfest application:
make installcheck-world: not tested
Implements feature: tested, passed
Spec compliant: not tested
Documentation: tested, passed
Manually tested uuidv7(), uuid_extract_time() – they work as expected. The basic docs provided look clear.
I haven't checked the tests though and possible edge cases, so leaving it as "needs review" waiting for more reviewers
