Note that the suffix <code>nd</code> stands for "no duplicates". Assume this method was done correctly.
'''Issue 1: Faulty CREATE WHERE clause'''
<code>ptoassigneend_allus</code> is the result of
<code>
CREATE TABLE ptoassigneend_allus AS
SELECT * FROM ptoassigneend
WHERE city ~* '.*\d{5}[-]\d{4}.*' OR addrline1 ~* '.*\d{5}[-]\d{4}.*' OR
addrline2 ~* '.*\d{5}[-]\d{4}.*' OR postcode ~* '.*\d{5}[-]\d{4}.*' OR
country ~* 'UNITED STATES';
</code>
It is unclear why this approach is favored over
<code>
CREATE TABLE ptoassigneend_allus AS
SELECT * FROM ptoassigneend
WHERE (city ~* '.*\d{5}[-]\d{4}.*' OR addrline1 ~* '.*\d{5}[-]\d{4}.*' OR
addrline2 ~* '.*\d{5}[-]\d{4}.*' OR postcode ~* '.*\d{5}[-]\d{4}.*') AND
country ~* 'UNITED STATES';
</code>
It appears that the country field is correct and that the country names are taken from a small lookup table.
'''Proof:'''

Therefore, my proposed modified <code>SELECT WHERE</code> is credible
<nowiki>
patent=# select count(*) from ptoassigneend;
count
---------
7234001
(1 row)
patent=# select count(*) from ptoassigneend where country = 'UNITED STATES';
count

(1 row)
patent=# select count(*) from ptoassigneend where country like '%UNITED STATES%';
count
---------
3570217
(1 row)
patent=# select * from ptoassigneend where (country like '%UNITED STATES%' and country != 'UNITED STATES');
