Description: ODBC driver 8.02.02 parses subqueries incorrectly
Details:

Problem description:

the ODBC driver seems confused by suqueries. e.g.

select test1.*, testsub.t1
from test1
left join
(select t1 from test2) as testsub

I get error from ODBC while debuging my code, saying returned E_FAIL. This
did not happen on version 8.0.

here is the ODBC log:

Global Options: Version='08.02.0200', fetch=100, socket=8192,
unknown_sizes=0, max_varchar_size=8192, max_longvarchar_size=32768
disable_optimizer=1, ksqo=1, unique_index=1,
use_declarefetch=0
text_as_longvarchar=0, unknowns_as_longvarchar=0,
bools_as_char=0 NAMEDATALEN=64
extra_systable_prefixes='dd_', conn_settings=''
conn_encoding='OTHER'

and errors logged just after the query:

conn=06430048, query='select nspname from pg_namespace n, pg_class c where
c.relnamespace=n.oid and c.oid='"select"'::regclass'
ERROR from backend during send_query: 'ERROR: relation "select" does not
exist'
STATEMENT ERROR: func=parse_statement, desc='', errnum=1, errmsg='Table not
found'

looks like function parse_statement didn't understand subquery, instead it
treats 'select' after 'join' as a table name.

* this query runs perfectly on pgAdmin.
