Re: Error when using unquoted identifier that contains the word end in a begin atomic block

I think your problem is somewhere on the client side.

For me, this works (in psql) with or without the double quotes:

regression=# CREATE OR REPLACE FUNCTION test_function_success() RETURNS TIMESTAMP
LANGUAGE SQL
BEGIN ATOMIC
  SELECT DISTINCT "effective_end_date"
                FROM test_view;
END;
CREATE FUNCTION
regression=# CREATE OR REPLACE FUNCTION test_function_success() RETURNS TIMESTAMP
LANGUAGE SQL
BEGIN ATOMIC
  SELECT DISTINCT effective_end_date
                FROM test_view;
END;
CREATE FUNCTION

I can't help noticing that the trailing END is missing from what you
show here, and it seems pretty clear that the syntax error is about
that, not about the effective_end_date identifier.  So the real
question is why the CREATE FUNCTION command is getting sent to the
server before it's complete.  If this isn't flat-out pilot error,
then I guess whatever client you are using (apparently not psql) is
getting confused about which occurrence of "end" terminates the
command.  You should take this up with the authors of said
client software.
