Best to ask your questions on the list, so others may find them,
with (hopefully) helpful answers in the archives in the future.

so, you've got a table with indistinguishable rows. I'm afraid you've
got to use an non ANSI extension. Every DB I've ever used has something
equivelant. In PostgreSQL, it's the 'oid', so in your case, you'd do:

SELECT oid,Name from tablename;

and see something like:
oid       Name 
-------  -------
102453   ibrahim      first row
102455   ibrahim      second row
103756   ibrahim      third row


Then, you can delete, comparing on the oid:

DELETE FROM tablename WHERE oid=102455;
