I understand well. But I would to respect similarity with PL/SQL. I
don't see reason for new special language for stored procedures that
is available only on PostgreSQL. And in this case Oracle PL/SQL CASE
statement is implementation of SQL/PSM CASE statement. Still SQL/PSM
isn't main language in PostgreSQL and isn't reason for fixation
plpgsql.

I prepare rpm and sources for 8.3 available from my archive and from
Devrim repository. There still some unsupported points - PostgreSQL
doesn't support all OOP features and some but not important things
depend on it (but I am not able to implement 100% clean SQL/PSM). And
than I will wait. Queue is full and I see lot of things with higher
priority than is SQL/PSM. I would to see real stored procedures in
8.4, but I don't belive.
