ALTER PROPERTY GRAPH <property_graph> ADD VERTEX TABLES (CUSTOMER) 

ALTER PROPERTY GRAPH <property_graph> ADD EDGE TABLES (KNOWS, STUDIES_AT)

ALTER PROPERTY GRAPH <property_graph> ADD VERTEX TABLES (CUSTOMER) EDGE TABLES (KNOWS, STUDIES_AT)

ALTER PROPERTY GRAPH <property_graph> DROP VERTEX TABLES (CUSTOMER)

ALTER PROPERTY GRAPH <property_graph> <table_name (or label?)> ADD PROPERTIES (name)

ALTER PROPERTY GRAPH <property_graph> <table_name (or label?)> DROP PROPERTIES (name)

ALTER PROPERTY GRAPH <property_graph> <table_name (or label?)> RENAME LABEL <new_label>
