## 52.44. pg_propgraph_property

The catalog pg_propgraph_property stores information about the properties in a property graph. This only stores information that applies to a property throughout the graph, independent of what label or element it is on. Additional information, including the actual expressions that define the properties are in the catalog [pg_propgraph_label_property](catalog-pg-propgraph-label-property.md).
