Update of doc TODO list for 7.0

Wow, the list is shrinking quickly:

---------------------------------------------------------------------------

> Add CmdTuples() to libpq++(Vince)

On its way.

> New CREATE CONSTRAINT TRIGGER and SET CONSTRAINTS commands(Jan)

No man page yet. Not sure what command SET CONSTRAINT applies to.

> First real FOREIGN KEY constraint trigger functionality (Jan)
> Add FOREIGN KEY ... MATCH FULL ... ON DELETE CASCADE (Jan)
> Add FOREIGN KEY ... MATCH referential actions (Don Baccus)

Jan has sent some. Are these done?

> Add ecpg EXEC SQL IFDEF, EXEC SQL IFNDEF, EXEC SQL ELSE, EXEC SQL ELIF
> and EXEC SQL ENDIF directives

ecpg.sgml?

> Updated user interfaces on initdb, initlocation, pg_dump, ipcclean (Peter E)

Need updating of switches.
