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.

# There is no correct way to write a rule that generates two files.
|
|
# Rules with two targets don't have that meaning, they are merely
|
|
# shorthand for two otherwise separate rules. If we have an action
|
|
# that in fact generates two or more files, we must choose one of them
|
|
# as primary and show it as the action's output, then make all of the
|
|
# other output files dependent on the primary, like this. Furthermore,
|
|
# the "touch" action is essential, because it ensures that gram.h is
|
|
# marked as newer than (or at least no older than) gram.c. Without that,
|
|
# make is likely to try to rebuild gram.h in subsequent runs, which causes
|
|
# failures in VPATH builds from tarballs.
