I copied-and-pasted your example, and it works fine for me on 7.0.*:

play=> insert into emp(empname, salary) values( 'test', 1000 );
INSERT 4576610 1
play=> insert into emp(empname, salary) values( 'test', -1);
ERROR:  test cannot have a negative salary

I suspect you messed up the installation of 'plpgsql' somehow.
Did you use the createlang script for that, or do it by hand?
