Error in 'psqlodbca.dll'

Hello,

 

I'm having a problem when I try to retrieve  records.

I'm using PostgreSQL 8.1 and a Delphi application.

When I try tro retrieve more than 300.000 records through Delphi application I receive an access violation in module 'psqlodbca.dll' .

 

Could you help-me?

 

Thanks,
