I was very surprised when all rows disappeared.

2. I use PostODBC v.06-40-0007, MS Access.
When I have access to a database, in log appear many messages:
"pq_recvbuf: unexpected EOF on client connection"
3. 
>From MS Access I use query like 'SELECT o.id,op.dt from o,op where  op.id=o.id AND op.dt=(select max(op2.dt) from op as op2 where op2.id=o.id);'. When query is executed 5 (or 6, or 7 i'm not sure) times, postmaster increase in size for 4kb (1 page?). For one day it increase for more than 2Mb. And I should restart postgres every night.
