- Each of the values specified in the partition bound specification is

- When creating a range partition, the lower bound specified with
- <literal>FROM</literal> is an inclusive bound, whereas the upper bound
- specified with <literal>TO</literal> is an exclusive bound. That is,
- the values specified in the <literal>FROM</literal> list are accepted
- values of the corresponding partition key columns in a given partition,
- whereas those in the <literal>TO</literal> list are not. To be precise,
- this applies only to the first of the partition key columns for which
- the corresponding values in the <literal>FROM</literal> and
- <literal>TO</literal> lists are not equal. All rows in a given
- partition contain the same values for all preceding columns, equal to
- those specified in <literal>FROM</literal> and <literal>TO</literal>
- lists. On the other hand, any subsequent columns are insignificant
- as far as implicit partition constraint is concerned.

- Specifying <literal>UNBOUNDED</literal> in <literal>FROM</literal>
- signifies <literal>-infinity</literal> as the lower bound of the

- as the upper bound when specified in <literal>TO</literal>.

- When creating a list partition, <literal>NULL</literal> can be specified
- to signify that the partition allows the partition key column to be null.
