Found the issue. Try out the included SQL.
I had honestly expected the second delete to work properly as nothing
had to be removed that table.
The rule was added as a temporary measure to protect the data
currently in the table -- without the intent of otherwise impeding the
other information's use. I suppose I forgot that the table wouldn't be
looked at as the rule is checked quite early.
CREATE TABLE junk_parent ( col SERIAL PRIMARY KEY
);
INSERT INTO junk_parent DEFAULT VALUES;
INSERT INTO junk_parent DEFAULT VALUES;
INSERT INTO junk_parent DEFAULT VALUES;
CREATE TABLE junk ( col int4 NOT NULL REFERENCES junk_parent(col) ON UPDATE CASCADE ON
DELETE CASCADE
);
INSERT INTO junk VALUES ('1');
DELETE FROM junk_parent WHERE col = 1;
DELETE FROM junk_parent WHERE col = 2;
