Subject: [PATCH] fix: ensure pg-client cache dir is writable before restore

actions/cache runs tar as the runner user, but /usr/lib/postgresql/
is root-owned, causing Permission denied errors on cache restore.
Pre-create the directory with correct ownership, and re-chown after
apt-get install so future cache saves work correctly.
