- <para>
- A property graph is a way to represent database contents, as an alternative
- to the usual (in SQL) approach of representing database contents using
- relational structures such as tables. A property graph can then be queried
- using graph pattern matching syntax, instead of join queries typical of
- relational databases. PostgreSQL implements SQL/PGQ<footnote><para>Here, PGQ
- stands for <quote>property graph query</quote>. In the jargon of graph
- databases, <quote>property graph</quote> is normally abbreviated as PG, which
- is clearly confusing for practitioners of PostgreSQL, also usually abbreviated
- as PG.</para></footnote>, which is part of the SQL standard, where a property
- graph is defined as a kind of read-only view over relational tables. So the
- actual data is still in tables or table-like objects, but is exposed as a
- graph for graph querying operations. (This is in contrast to native graph
- databases, where the data is stored directly in a graph structure.)
- Underneath, both relational queries and graph queries use the same query
- planning and execution infrastructure, and in fact relational and graph
- queries can be combined and mixed in single queries.
- </para>
-
- <para>
- A graph is a set of vertices and edges. Each edge has two distinguishable
- associated vertices called the source and destination vertices. (So in
- this model, all edges are directed.) Vertices and edges together are
- called the elements of the graph. A property graph extends this well-known
- mathematical structure with a way to represent user data. In a property
- graph, each vertex or edge has one or more associated labels, and each
- label has zero or more properties. The labels are similar to table row
- types in that they define the kind of the contained data and its structure.
- The properties are similar to columns in that they contain the actual data.
- In fact, by default, a property graph definition exposes the underlying
- tables and columns as labels and properties, but more complicated
- definitions are possible.
- </para>
-
- <para>
- Consider the following table definitions:
-<programlisting>
-CREATE TABLE products (
- product_no integer PRIMARY KEY,
- name varchar,
- price numeric
-);
-
-CREATE TABLE customers (
- customer_id integer PRIMARY KEY,
- name varchar,
- address varchar
-);
-
-CREATE TABLE orders (
- order_id integer PRIMARY KEY,
- ordered_when date
-);
-
-CREATE TABLE order_items (
- order_items_id integer PRIMARY KEY,
- order_id integer REFERENCES orders (order_id),
- product_no integer REFERENCES products (product_no),
- quantity integer
-);
-
-CREATE TABLE customer_orders (
- customer_orders_id integer PRIMARY KEY,
- customer_id integer REFERENCES customers (customer_id),
- order_id integer REFERENCES orders (order_id)
-);
-</programlisting>
- When mapping this to a graph, the first three tables would be the vertices
- and the last two tables would be the edges. The foreign-key definitions
- correspond to the fact that edges link two vertices. (Graph definitions
- work more naturally with many-to-many relationships, so this example is
- organized like that, even though one-to-many relationships might be used
- here in a pure relational approach.)
- </para>
-
- <para>
- Here is an example how a property graph could be defined on top of these
- tables:
-<programlisting>
-CREATE PROPERTY GRAPH myshop
- VERTEX TABLES (
- products,
- customers,
- orders
- )
- EDGE TABLES (
- order_items SOURCE orders DESTINATION products,
- customer_orders SOURCE customers DESTINATION orders
- );
-</programlisting>
- </para>
-
- <para>
- This graph could then be queried like this:
-<programlisting>
--- get list of customers active today
-SELECT customer_name FROM GRAPH_TABLE (myshop
- MATCH (c IS customers)-[IS customer_orders]->(o IS orders WHERE o.ordered_when = current_date)
- COLUMNS (c.name AS customer_name));
-</programlisting>
- corresponding approximately to this relational query:
-<programlisting>
--- get list of customers active today
-SELECT customers.name FROM customers JOIN customer_orders USING (customer_id) JOIN orders USING (order_id) WHERE orders.ordered_when = current_date;
-</programlisting>
- </para>
-
- <para>
- The above definition requires that all tables have primary keys and that
- for each edge there is an appropriate foreign key. Otherwise, additional
- clauses have to be specified to identify the key columns. For example,
- this would be the fully verbose definition that does not rely on primary
- and foreign keys:
-<programlisting>
-CREATE PROPERTY GRAPH myshop
- VERTEX TABLES (
- products KEY (product_no),
- customers KEY (customer_id),
- orders KEY (order_id)
- )
- EDGE TABLES (
- order_items KEY (order_items_id)
- SOURCE KEY (order_id) REFERENCES orders (order_id)
- DESTINATION KEY (product_no) REFERENCES products (product_no),
- customer_orders KEY (customer_orders_id)
- SOURCE KEY (customer_id) REFERENCES customers (customer_id)
- DESTINATION KEY (order_id) REFERENCES orders (order_id)
- );
-</programlisting>
- </para>
-
- <para>
- As mentioned above, by default, the names of the tables and columns are
- exposed as labels and properties, respectively. The clauses <literal>IS
- customer</literal>, <literal>IS order</literal>, etc. in the
- <literal>MATCH</literal> clause in fact refer to labels, not table names.
- </para>
-
- <para>
- One use of labels is to expose a table through a different name in the graph.
- For example, in graphs, vertices typically have singular nouns as labels and
- edges typically have verbs or phrases derived from verbs as labels, such as
- <quote>has</quote>, <quote>contains</quote>, or something specific like
- <quote>approved_by</quote>. We can introduce such labels into our example like
- this:
-<programlisting>
-CREATE PROPERTY GRAPH myshop
- VERTEX TABLES (
- products LABEL product,
- customers LABEL customer,
- orders LABEL "order"
- )
- EDGE TABLES (
- order_items SOURCE orders DESTINATION products LABEL contains,
- customer_orders SOURCE customers DESTINATION orders LABEL has_placed
- );
-</programlisting>
- </para>
-
- <para>
- With this definition, we can write a query like this:
-<programlisting>
-SELECT customer_name FROM GRAPH_TABLE (myshop
- MATCH (c IS customer)-[IS has_placed]->(o IS "order" WHERE o.ordered_when = current_date)
- COLUMNS (c.name AS customer_name));
-</programlisting>
- With the new labels the <literal>MATCH</literal> clause is now more intuitive.
- </para>
-
- <para>
- Notice that the label <literal>order</literal> is quoted. If we run above
- statements without adding quotes around <literal>order</literal>, we will get
- a syntax error since <literal>order</literal> is a keyword.
- </para>
-
- <para>
- Another use is to apply the same label to multiple element tables. For
- example, consider this additional table:
-<programlisting>
-CREATE TABLE employees (
- employee_id integer PRIMARY KEY,
- employee_name varchar,
- ...
-);
-</programlisting>
-and the following graph definition:
-<programlisting>
-CREATE PROPERTY GRAPH myshop
- VERTEX TABLES (
- products LABEL product,
- customers LABEL customer LABEL person PROPERTIES (name),
- orders LABEL "order",
- employees LABEL employee LABEL person PROPERTIES (employee_name AS name)
- )
- EDGE TABLES (
- order_items SOURCE orders DESTINATION products LABEL contains,
- customer_orders SOURCE customers DESTINATION orders LABEL has
- );
-</programlisting>
- (In practice, there ought to be an edge linking the
- <literal>employees</literal> table to something, but it is allowed like
- this.) Then we can run a query like this (incomplete):
-<programlisting>
-SELECT ... FROM GRAPH_TABLE (myshop
- MATCH (IS person WHERE name = '...')-[]->...
- COLUMNS (...));
-</programlisting>
- This would automatically consider both the <literal>customers</literal> and
- the <literal>employees</literal> tables when looking for an edge with the
- <literal>person</literal> label.
- </para>
-
- <para>
- When more than one element table has the same label, it is required that
- the properties match in number, name, and type. In the example, we specify
- an explicit property list and in one case override the name of the column
- to achieve this.
- </para>
-
- <para>
- Using more than one label associated with an element table and each label
- exposing a different set of properties, the same relational data, and the
- graph structure contained therein, can be exposed through multiple
- co-existing logical views, which can be queried using graph pattern matching
- constructs.
- </para>

- MATCH (c IS customers)-[IS customer_orders]->(o IS orders WHERE o.ordered_when = current_date)
- COLUMNS (c.name AS customer_name));
-</programlisting>
- The graph query part happens inside the <literal>GRAPH_TABLE</literal>
- construct. As far as the rest of the query is concerned, this acts like a
- table function in that it produces a computed table as output. Like other
- <literal>FROM</literal> clause elements, table alias and column alias
- names can be assigned to the result, and the result can be joined with
- other tables, subsequently filtered, and so on, for example:
-<programlisting>
-SELECT ... FROM GRAPH_TABLE (mygraph
- MATCH ...
- COLUMNS (...)) AS myresult (a, b, c) JOIN othertable USING (a) WHERE b > 0 ORDER BY c;
-</programlisting>
- </para>
-
- <para>
- The <literal>GRAPH_TABLE</literal> clause consists of the graph name,
- followed by the keyword <literal>MATCH</literal>, followed by a graph
- pattern expression (see below), followed by the keyword
- <literal>COLUMNS</literal> and a column list.
- </para>
- </sect2>

- <sect2 id="queries-graph-patterns">
- <title>Graph Patterns</title>
-
- <para>
- The core of the graph querying functionality is the graph pattern, which
- appears after the keyword <literal>MATCH</literal>. Formally, a graph
- pattern consists of one or more path patterns. A path is a sequence of
- graph elements, starting and ending with a vertex and alternating between
- vertices and edges. A path pattern is a syntactic expression that
- matches paths.
- </para>
-
- <para>
- A path pattern thus matches a sequence of vertices and edges. The
- simplest possible path pattern is
-<programlisting>
-()
-</programlisting>
- which matches a single vertex. The next simplest pattern would be
-<programlisting>
-()-[]->()
-</programlisting>
- which matches a vertex followed by an edge followed by a vertex. The
- characters <literal>()</literal> are a vertex pattern and the characters
- <literal>-[]-></literal> are an edge pattern.
- </para>
-
- <para>
- These characters can also be separated by whitespace, for example:
-<programlisting>
-( ) - [ ] - > ( )
-</programlisting>
- </para>
-
- <tip>
- <para>
- A way to remember these symbols is that in visual representations of
- property graphs, vertices are usually circles (like
- <literal>()</literal>) and edges have rectangular labels (like
- <literal>[]</literal>).
- </para>
- </tip>
-
- <para>
- The above patterns would match any vertex, or any two vertices connected
- by any edge, which isn't very interesting. Normally, we want to search
- for elements (vertices and edges) that have certain characteristics.
- These characteristics are written in between the parentheses or brackets.
- (This is also called an element pattern filler.) Typically, we would
- search for elements with a certain label. This is written by <literal>IS
- <replaceable>labelname</replaceable></literal>. For example, this would
- match all vertices with the label <literal>person</literal>:
-<programlisting>
-(IS person)
-</programlisting>
- The next
- example would match a vertex with the label <literal>person</literal>
- connected to a vertex with the label <literal>account</literal> connected
- by an edge with the label <literal>has</literal>.
-<programlisting>
-(IS person)-[IS has]->(IS account)
-</programlisting>
- Multiple labels can also be matched, using <quote>or</quote> semantics:
-<programlisting>
-(IS person)-[IS has]->(IS account|creditcard)
-</programlisting>
- </para>
-
- <para>
- Recall that edges are directed. The other direction is also possible in a
- path pattern, for example:
-<programlisting>
-(IS account)<-[IS has]-(IS person)
-</programlisting>
- It is also possible to match both directions:
-<programlisting>
-(IS person)-[IS is_friend_of]-(IS person)
-</programlisting>
- This has a meaning of <quote>or</quote>: An edge in either direction would
- match.
- </para>
-
- <para>
- In many cases, the edge patterns don't need a filler. (All the filtering
- then happens on the vertices.) For these cases, an abbreviated edge
- pattern syntax is available that omits the brackets, for example:
-<programlisting>
-(IS person)->(IS account)
-(IS account)<-(IS person)
-(IS person)-(IS person)
-</programlisting>
- As is often the case, abbreviated syntax can make expressions more compact
- but also sometimes harder to understand.
- </para>
-
- <para>
- Furthermore, it is possible to define graph pattern variables in the path
- pattern expressions. These are bound to the matched elements and can be
- used to refer to the property values from those elements. The most
- important use is to use them in the <literal>COLUMNS</literal> clause to
- define the tabular result of the <literal>GRAPH_TABLE</literal> clause.
- For example (assuming appropriate definitions of the property graph as
- well as the underlying tables):
-<programlisting>
-GRAPH_TABLE (mygraph
- MATCH (p IS person)-[h IS has]->(a IS account)
- COLUMNS (p.name AS person_name, h.since AS has_account_since, a.num AS account_number))
-</programlisting>
- <literal>WHERE</literal> clauses can be used inside element patterns to
- filter matches:
-<programlisting>
-(IS person)-[IS has]->(a IS account WHERE a.type = 'savings')
-</programlisting>

-
- <para>
- <command>CREATE PROPERTY GRAPH</command> defines a property graph. A
- property graph consists of vertices and edges, together called elements,
- each with associated labels and properties, and can be queried using the
- <literal>GRAPH_TABLE</literal> clause of <xref linkend="sql-select"/> with
- a special path matching syntax. The data in the graph is stored in regular
- tables (or views, foreign tables, etc.). Each vertex or edge corresponds
- to a table. The property graph definition links these tables together into
- a graph structure that can be queried using graph query techniques.
- </para>
-
- <para>
- <command>CREATE PROPERTY GRAPH</command> does not physically materialize a
- graph. It is thus similar to <command>CREATE VIEW</command> in that it
- records a structure that is used only when the defined object is queried.
- </para>
-
- <para>
- If a schema name is given (for example, <literal>CREATE PROPERTY GRAPH
- myschema.mygraph ...</literal>) then the property graph is created in the
- specified schema. Otherwise it is created in the current schema.
- Temporary property graphs exist in a special schema, so a schema name
- cannot be given when creating a temporary property graph. Property graphs
- share a namespace with tables and other relation types, so the name of the
- property graph must be distinct from the name of any other relation (table,
- sequence, index, view, materialized view, or foreign table) in the same
- schema.

- chosen label names can be specified. (Label names do not have to be
- unique across a property graph. It can be useful to assign the same
- label to different elements.) Each label has a list (possibly empty) of
- properties. By default, all columns of a table are automatically
- exposed as properties. This can be specified explicitly as
- <literal>PROPERTIES ALL COLUMNS</literal>. Alternatively, a list of

---Test RLS with GRAPH_TABLE
---
---This test verifies that Row Level Security (RLS) policies are correctly
---enforced when querying tables underlying property graphs using GRAPH_TABLE.
---graph_table.sql has extensive tests covering interaction of GRAPH_TABLE with
---other query constructs. rowsecurity.sql has extensive coverage of interaction
---of RLS and other features of PostgreSQL. This test along with those two tests
---is sufficient to make sure that all combinations of RLS and GRAPH_TABLE will
---work as expected.
