Here's something I've just noticed: CREATE TABLE foo (f INTEGER PRIMARY KEY); INSERT INTO foo VALUES (1); CREATE TABLE bar (b INTEGER REFERENCES foo); CREATE TABLE bar1 () INHERITS (bar); INSERT INTO bar1 VALUES (1);
This is quite correct: TRUNCATE foo; ERROR: cannot truncate a table referenced in a foreign key constraint DETAIL: Table "bar" references "foo". HINT: Truncate table "bar" at the same time, or use TRUNCATE ... CASCADE. But: TRUNCATE foo, bar; SELECT * FROM bar; b --- 1 (1 row) SELECT * FROM foo; f --- (0 rows) Whoops. The referential constraint has been violated. Perhaps it's a good idea to extend TRUNCATE on a parent table to all children? -- Florian Weimer <[EMAIL PROTECTED]> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99 ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
