No, it isn't -- PL/PgSQL is not defined by the SQL standard. I guess
you're referring to SQL/PSM, but that has only a passing resemblance to
PL/PgSQL. Implementing SQL/PSM in some form would definitely be worth
doing (especially now that MySQL have), but I haven't seen any plans to
do that by adapting PL/PgSQL to SQL/PSM.
In any case, there are plenty of cases in which we accept a superset of
the syntax defined by the SQL standard -- DROP TABLE { RESTRICT |
CASCADE }, for example. We have never interpreted compliance with the
SQL specification to mean that we must *only* accept the standard's
syntax and nothing else.
