By accident I stumbled across the following paragraph in the August
2002 draft of SQL 2003:

	If there are multiple instances of <next value expression>s
	specifying the same sequence generator within a single
	SQL-statement, all those instances return the same value for a
	given row processed by that SQL-statement.

Is this of any relevance to PG's nextval()?
