The following bug has been logged on the website:
Bug reference: 7711
Logged by: Michael Kolomeitsev
Email address: [email protected]
PostgreSQL version: 9.2.1
Operating system: Arch Linux
Description:
It seems multiple dots (".") are not allowed. For example: a.b.c := value;
How to reproduce:
CREATE TABLE nodes (
id SERIAL NOT NULL PRIMARY KEY,
name TEXT NOT NULL
);
CREATE TYPE pathId AS (
id INTEGER,
node nodes
);
CREATE OR REPLACE FUNCTION test_AEN7304() RETURNS void AS $$
DECLARE
r pathId;
n nodes;
BEGIN
n.name := 'abc';
r.id := 1;
r.node := n; -- All is ok
r.node.name := 'def'; -- << Error here
-- (r).node.name := 'def'; -- << and here
-- ((r).node).name := 'def'; -- << and here
END;
$$ LANGUAGE 'plpgsql';
ERROR: "r.node.name" is not a known variable
