One limitation is that indexes can not be created on columns longer
than about 2,000 characters. Fortunately, such indexes are rarely
needed. Uniqueness is best guaranteed by a funtion index of an MD5
needed. Uniqueness is best guaranteed by a function index of an MD5
hash of the long column, and full text indexing allows for searching
of words within the column.

4.12) What is an OID? What is a CTID?
Every row that is created in PostgreSQL gets a unique OID unless
created WITHOUT OIDS. OIDs are autotomatically assigned unique 4-byte
created WITHOUT OIDS. OIDs are automatically assigned unique 4-byte
integers that are unique across the entire installation. However, they
overflow at 4 billion, and then the OIDs start being duplicated.
PostgreSQL uses OIDs to link its internal system tables together.
