Problem with constraint unique.

I apologies for bothering your team, before send this message we google the problem and was not able to find any tips about it. Our project encounter with quite strange situation where we found violation of unique constraint of primary key. We have a table that has an attribute ID as PK. The table name enerstorymain_task_info. Surprisingly the query 
select id, count(*) from    enerstroymain_task_info group by 1 having count(*) > 1
return a lot of rows. Than we rechecked PK it is ok. So we supposed that some how we had dropped the PK and then created duplicates and than rebuild the PK, but in this case PK would not rebuild. To avoid any weird settings I run the query from PGAdmin and DBView from different computers. Also I doubt that any kind problem like repeatable red could be the reason due to insert operation is done only a server without any complicated query. I mean simple INSERT INTO ….
The only strange thing is that the table is really width. 
 
In the file i upload some rows that i get using the query:
select * from enerstroymain_task_info eti where id in (
select id from enerstroymain_task_info group by id having count (*)> 1
) limit 6
 
Here is DDL of the table
