Implementation of SQL property graph queries, according to SQL/PGQ standard (ISO/IEC 9075-16:2023). This adds: - GRAPH_TABLE table function for graph pattern matching - DDL commands CREATE/ALTER/DROP PROPERTY GRAPH - several new system catalogs and information schema views - psql \dG command - pg_get_propgraphdef() function for pg_dump and psql A property graph is a relation with a new relkind RELKIND_PROPGRAPH. It acts like a view in many ways. It is rewritten to a standard relational query in the rewriter. Access privileges act similar to a security invoker view. (The security definer variant is not currently implemented.) Starting documentation can be found in doc/src/sgml/ddl.sgml and doc/src/sgml/queries.sgml.
