dblink_exec: can it perform a remote function?

Hi all

I am trying to execute a function on a remote server using dblink to
test stuff.

My function is:
create or replace function /*LOGGER.*/WARN(in P_MESSAGE text)
    returns void as
$warn$
begin
       raise debug     '%', P_MESSAGE;
       raise log       '%', P_MESSAGE;
       raise info      '%', P_MESSAGE;
       raise notice    '%', P_MESSAGE;
       raise warning   '%', P_MESSAGE;
end;
$warn$ language PLPGSQL;

I try to execute it with:
do language PLPGSQL
$anonymous$
begin
       set session client_min_messages to log;
       perform dblink_connect_u('pragma','dbname=thiemo password=XXX');
       perform dblink_exec('pragma','perform WARN(P_MESSAGE := ''Raise
dblink test'');');
       perform dblink_exec('pragma','commit;');
       perform dblink_disconnect('pragma');
end;
$anonymous$

I get the error:
psql:test_02.sql:22: ERROR:  syntax error at or near "perform"
CONTEXT:  Error occurred on dblink connection named "pragma": could not
execute command.
SQL statement "SELECT dblink_exec('pragma','perform WARN(P_MESSAGE :=
''Raise dblink test'');')"
PL/pgSQL function inline_code_block line 12 at PERFORM

If I try to execute it with:
do language PLPGSQL
$anonymous$
begin
       set session client_min_messages to log;
       perform dblink_connect_u('pragma','dbname=thiemo password=XXX');
       perform dblink_exec('pragma','select WARN(P_MESSAGE := ''Raise
dblink test'');');
       perform dblink_exec('pragma','commit;');
       perform dblink_disconnect('pragma');
end;
$anonymous$

Isn't it possible to execute funtions through dblink? Any hint is
appreciated.

Kind regards

Thiemo
