Uid 31 is reserved forever (speaking as the base-passwd maintainer), but
new installations of postgresql should have a uid in the system range,
namely 100-999, as created by 'adduser --system'. See the changelog for
base-passwd 3.5.0.

No, you should definitely not attempt to fall back to useradd: that
whole subthread is just a distraction. Pre-depending on adduser is
perfectly fine and reasonable for a package like postgresql, and it is
wrong for a Debian package to try to use anything else other than
adduser to create system users. Using adduser means that we, or local
sysadmins, only have one thing to change if we need to change how system
users work.

Use adduser. It's your friend.
