Yes that helped!
reindex index users_email_address_text_key;
UPDATE users set email_address_text=email_address;
It kind of works now. Or at least it does not result in error. The UPDATE query is running for more than an hour and still hasn't return. This is inline
with what we have seen before that coping 1 million fields seems to be
excessively slow.
About the index, it is created implicitly because of the UNIQUE constraint. At this point right after the column is added, they are all null.

index? if so, what happenned if you REINDEX the table or even DROP and
CREATE the index again? it certainly sounds to an index corruption.
