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?
