The 'Resource[]' syntax is a resource reference, whereas 'resouce {}' is
the declaration syntax -
See
https://docs.puppet.com/puppet/latest/reference/lang_data_resource_reference.html
and
https://docs.puppet.com/puppet/latest/reference/lang_resources.html#simplified-syntax
With regards to erroring, you don't need to do anything special, other than
setup the relationship using 'before/requires' between the Logical_Volume
resource and the Postgresql class.
If the Logical_Volume resource fails to apply, then Puppet will skip the
Postgresql class.
Also, you don't need to explicitly order the LVM PV<>VG<>LV resources, as
they already setup the requires dependencies in the resource providers -
See
https://docs.puppet.com/puppet/latest/reference/lang_relationships.html#auto-relationships
