Yes - in the postgresql.conf there is an "add_missing_from" option - change
that to false. I think by default it is on, and in future versions they are
planning to set that to false.

Subject: [NOVICE] Aliased table names ...oddity?
PostgreSQL-7.4.5
I don't know whether this is a 'bug' (it seems like designed behaviour)
- but if you do:
SELECT markUp.*
FROM markUp AS mark
JOIN clientBranch AS clntB
ON mark.foreignRecNo = clntB.clientRecNo
AND clntB.recNo = 2
WHERE mark.serviceCoBranchRecNo = 2
AND mark.foreignTableName = 'client'
So the table has an ALIAS that is ignored in the SELECT clause, then the
WHERE clause is 'ignored' and all rows from the table are returned.
Obviously its a typo in the original SQL - (but one that's very difficult to
pick up unless the data returned is obviously outside limits). Running the
SQL in PSQL, it seems that a FROM clause is automatically appended for the
missing 'markUp' table - so it does seem that this is intentional. Is there
a way to have this 'rejected' as an error - ie selecting from a table not
included in the query?
