However, they are not sets and have quite different semantics to the data type that we are asking you to implement. Note that arrays in PostgreSQL have some properties and operations that make them look a little bit like sets. You may implement the functions for the data type in any way you like, provided that they satisfy the semantics given below (in the intSets section). In this assignment, we will be adding a new data type for dealing with sets of integers. It also means that PostgreSQL is the database of choice in research projects which aim to push the boundaries of what kind of data a DBMS can manage. This capability has led to the development by PostgreSQL users of a number of types (such as polygons) which have become part of the standard distribution. PostgreSQL has an extensibility model which, among other things, provides a well-defined process for adding new data types into a PostgreSQL server. (typically /srvr/ YOU/pgsql/log) Introduction (typically /srvr/ YOU/pgsql/data) PG_LOG the file where you send PostgreSQL’s log output (typically /srvr/ YOU/pgsql) PG_DATA the directory where you have placed PostgreSQL’s data (typically /srvr/ YOU/postgresql-10.4) PG_HOME the directory where you have installed the PostgreSQL binaries

We use the following names in the discussion below: PG_CODE the directory where your PostgreSQL source code is located Questions which indicate that you haven’t done this will simply get the response “Please read the spec”. Make sure that you read this assignment specification carefully and completely before starting work on the assignment. The goal is to implement a new data type for PostgreSQL, complete with input/output functions and a range of operations.
