pg_propgraph_property

PostgreSQL documentation ↗Source definition ↗

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.

`oid`	`oid`NOT NULL	Row identifier
`pgppgid`	`oid`NOT NULL	Reference to the property graph that this property belongs toReferences:`pg_class.oid`
`pgpname`	`name`NOT NULL	The name of the property. This is unique among the properties in a graph.
`pgptypid`	`oid`NOT NULL	The data type of this property. (This is required to be fixed for a given property in a property graph, even if the property is defined multiple times in different elements and labels.)References:`pg_type.oid`
`pgptypmod`	`integer`NOT NULLDocumented as:`int4`	typmod to be applied to the data type of this property. (This is required to be fixed for a given property in a property graph, even if the property is defined multiple times in different elements and labels.)
`pgpcollation`	`oid`NOT NULL	The defined collation of this property, or zero if the property is not of a collatable data type. (This is required to be fixed for a given property in a property graph, even if the property is defined multiple times in different elements and labels.)References:`pg_collation.oid`

Columns marked "implicit" are not included in SELECT *; some early statistics views are completed from same-version source, and the extra provenance is shown in the column description.

9.0 is the coverage baseline; a column already present in the baseline is not marked as added. The matrix aligns columns by name, so a rename appears as the old column removed and a new column added.
