There are at least a couple of versions claiming to be maintained (including the one linked above), but only this one actually seems like maybe it is (which seems more actively maintained than phpPgAdmin2): GitHub - ReimuHakurei/phpPgAdmin: Actively maintained fork of phpPgAdmin.
We’ll need to do some research and figure out what’s going on with that. The original phpPgAdmin was being maintained by the Postgres project folks, which seemed trustworthy, but we obviously can’t keep offering something that requires an EOL PHP version.
