Tab complete for CREATE OR REPLACE TRIGGER statement

Hi, Hackers.

 Yesterday, OR REPLACE clause was provided to the CREATE TRIGGER statement, so I wrote a patch for tab completion for
thepsql command. 
TRIGGER adds tab completion to the CREATE OR REPLACE statement, and the CREATE TRIGGER and CREATE OR REPLACE TRIGGER
statementsare completed in the same way. 
I referred to the tab completion code of the CREATE RULE statement.
