ERROR: plpgsql: cache lookup from pg_proc failed

From

Date:
If I run the following script:
 
create function functst() returns int4 as '
begin
return 1;
end;
' language 'plpgsql';
select functst() as rc;
 
I get:
 
DROP
CREATE
ERROR: plpgsql: cache lookup from pg_proc failed
 
Could someone explain what is causing this error?
 
TIA,
