hello all

this is the problem:

example:

test=> CREATE TABLE MAN(name char(10) UNIQUE PRIMARY KEY);T

test=> CREATE TABLE PROFESSOR(scool char(20))INHERITS(MAN);

test=> INSERT INTO PROFESSOR(name) VALUES('DAVIS');
INSERT 54424 1

test=> INSERT INTO PROFESSOR(name) VALUES('DAVIS');
INSERT 54425 1

Yikes, I see what you mean.  Added to TODO:

* Unique index on base column not honored on inserts from inherited table
  INSERT INTO inherit_table (unique_index_col) VALUES (dup) should fail
