You're looking for 'Requires' -
See https://docs.puppet.com/puppet/latest/reference/lang_relationships.html
Basically, you can add "requires => Logical_Volume['lv_pgdata']" to the
'postgresql::server' class, and if the Logical_Volume resource fails for
whatever reason, then the 'postgresql::server' class will be skipped...
