Description
Builds a single object (instance of class) from the row
in table table-name with the given object id, oid.
In PostgresQL, every row (tuple) in the entire system has a unique
identity. This is like object identity. (And, like object identity
encoded in pointers, may be reused for a new row after the row is deleted).
