Yes:

https://wiki.postgresql.org/wiki/Apt

"Note: This repository provides "postgresql", "postgresql-contrib", and
"postgresql-client" meta-packages that depend on the latest
postgresql-x.y, ... packages, similar to the ones present in Debian and
Ubuntu. Once a new PostgreSQL version is released, these meta-packages
will be updated to depend on the new version. If you rather want to stay
with a particular PostgreSQL version, you should install specific
packages like "postgresql-11" instead of "postgresql". "
