Description

This is the grammar copied from SQL-2011:

<row type> ::=
  ROW <row type body>
<row type body> ::=
  <left paren> <field definition> [ { <comma> <field definition> }... ] <right paren>

<field definition> ::=
  <field name> <data type>

We extend the grammar for every field data type to have an optional suffix:

<field definition> ::=
  <field name> <data type> [ [ NULL | NOT NULL] ]

The suffix is used to indicate if this field is nullable; To keep sync with other data types, the default is not nullable.
