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()?
