The reason this happens is because both ALTER OPERATOR and ALTER
OPERATOR CLASS are supported so for the third word you would have to do
tab complete only when the C-L-A-S-S is unique. I suppose you could say
as soon as they type 'C' it can't match an operator name but it hardly
seems worth the complexity.

CREATE CONSTRAINT TRIGGER is not supported because it is designed to be
used only by pg_dump and is not for general use. I added a source file
comment mentioning why we don't support tab completion for it.
