Description: REFERENCES doesn't work on Inherited Tables
Details:
The inserting of a row into a table doesn't reflect in the mother table
when the mother table is referenced from a third one.
Example
'a' is the mother table, 'b' is the child, and there is a reference to 'a'
in table 'c'
create table a( id INT UNIQUE, name VARCHAR);
create table b( foofoo INT) INHERITS(a);
create table c (id INT UNIQUE, bar INT, foo INT REFERENCES "a"("id"));
insert into b VALUES (1,'first',0);
insert into b VALUES (2,'second',3);
Then inserting into 'c'
insert into c values (1,3,2);
and the result is unfortunately:
$1 referential integrity violation - key referenced from c not found in a
which means, that id=2 is not in table 'a'.

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
