Look that package postgresql-client-13 appears with "iF" state (configuration failed) and other failed packages with "iU" state
dpkg -l | grep postgres
iU postgresql 13+225 all object-relational SQL database (supported version)
iU postgresql-13 13.5-0+deb11u1 amd64 The World's Most Advanced Open Source Relational Database
iF postgresql-client-13 13.5-0+deb11u1 amd64 front-end programs for PostgreSQL 13
ii postgresql-client-common 225 all manager for multiple PostgreSQL client versions
ii postgresql-common 225 all PostgreSQL database-cluster manager
Second letter -> current package state:
i ... installed
U ... unpacked
F ... half-configured (configuration failed for some reason)

I removed all PostgreSQL packages and all files with: sudo apt purge postgresql
After that I tried again to install postgresql-client-13, which returned the error above. sudo apt install postgresql-client-13

Solution
The problem is related to the existence of the previously installed snoopy package.
Uninstall snoopy with sudo apt remove snoopy and, after that install PostgreSQL or postgresql-client-13.
