Hi all,

Thank you all  for your prompt replies.

I tried about all the versions I could find (ranging from 7.3.200 to 
till and they all gave the same trouble.
Then I tried the latest snapshot,,and youhouuuuu, it worked!!! 
Me a very happy man.
I'm not sure what you did we these dlls, but I just pulled in a +/- 25 
milj row table in sas through the odbc (is against a postgresql 8.0.3 
amd64 on freebsd 6.0) and it worked perfectly. Memory consumption never 
went over 45M in windows. The table takes up 8.6GB of harddisk space in 

Just for future references (in case someone ever has the same error), I 
used the following settings:

with the following options:
- disable genetic optimizer
- Recognize Uniq Index
- Use Declare/Fetch
- Inknown sizes: max
- Bools as char
- maxvarchar: 254
- cache: 100
- max long varchar: 8190
- systableprefixes: dd_;
- show system tables
- LF <-> CR/LF
- row versioning
- int8 as default
- protocol >= 6.4
- OID options: show column & fake index

Thanks again,
