Re: link tables with VB from Access fails with 7.3.01 Unicode

Thanks Jean for the info. I'd somewhere read that there are length 
restrictions in the connect string and that we should not use this kind 
of parameters, but anyway it DID NOT WORK with this either.
But you use the "normal" Postgres driver and not the unicode (beta) 
driver, so maybe it is related with the driver.
The issue is that it did work BEFORE version 7.03.01 so something in the 
new versions (7.01 and 7.02) has triggered this.
