I'm trying to migrate from 7.3.4 to 7.4.1. I've performed a pg_dumpall using the pg_dumpall from 7.4.1. Once 7.4 is running and I try to import the dump, I get the following error:
psql:pgsql.dump:301: ERROR: column "r.day" must appear in the GROUP BY clause or be used in an aggregate function
The SQL it's choking on is:
CREATE VIEW maillog_day_tally AS
SELECT
day,
COALESCE(sum(r.tally), 0) AS received,
COALESCE(sum(s.tally), 0) AS sent
FROM
maillog_recv r FULL JOIN maillog_sent s USING (day, address)
GROUP BY day;The tables:
CREATE TABLE maillog_sent (
day date NOT NULL,
tally integer NOT NULL,
address text NOT NULL,
CONSTRAINT maillog_sent_pk PRIMARY KEY (day, address)
);CREATE TABLE maillog_recv (
day date NOT NULL,
tally integer NOT NULL,
address text NOT NULL,
CONSTRAINT maillog_recv_pk PRIMARY KEY (day, address)
);Of course if I change the query to read "SELECT r.day ..." it will parse, however, I need to be able to select the day column from the result of the JOIN, not just from one of the two tables.
I'm at a loss to explain why 7.4 is treating that SELECT query differently than previous versions. I can't see anything in the 7.4 release notes that would help explain this. Can anyone provide any insight?
