From excellent Momjian's online book (URL for the extract is
http://www.ca.postgresql.org/docs/aw_pgsql_book/node71.html):
"Every row in POSTGRESQL is assigned a unique, normally invisible number
called an object identification number (OID). When the software is
initialized with initdb, a counter is created and set to approximately
seventeen-thousand. The counter is used to uniquely number every row.
Although databases may be created and destroyed, the counter continues to
increase. It is used by all databases, so identification numbers are always
unique. No two rows in any table or in any database will ever have the same
object ID."
So you can't have a view with the same OID, use another primary key instead.
The index for the book is

from there!! Check it.
