upgrade problem - Mailing list pgsql-hackers

Dear Sir/Madam,

After Upgrade Database to the latest version I got some problem like this
1. ODBC connection I used to link table from postgresql to my database file (MS
Access) but now I cannot and it gives me error "Invalid field definition
'accont' in definition of index or relationship" 

2. Cannot execute some query which I could excute before upgrade.
the query is complicate but it used to work well both with MS Access
and with db prompt it returned me error like it terminated my query
abnormally i.e. "Memory exhausted in AlloSetAlloc() (#1)",
"No response from the backend, Socket has been closed (#1)".

my sql is .. 
"select date(s.stop) as accdate,sum(date_part('epoch',s.stop-s.start)/3600)
,sum((s.rate/t.rate)*date_part('epoch',s.stop-s.start)/3600)
,sum(s.value*100/107),sum(t.balance)
from session s,ticket t 
where s.stop is not null and date(s.stop) between '1999/06/01' and
'1999/06/15' group by accdate;"

3.Some query work abnormally since upgrade. 

I did attached the infomation I have

Table Schema which I use in my query in 2. and I used to link it
into my Access Database file.
