We are trying to retrieve a longvarchar field that exceeds 65K using a PVSW 9.5 database with Delphi 7. 65K and less is not a problem. We have tried both PDAC and ADO components. Neither work, although the ADO component does retreive large objects on v10.x. ADO component on 9.5 returns an empty string. Any help appreciated.

Does PDAC also return an empty string? If not, how does it fail?

Also, with the ADO components are you using OLEDB or ODBC?  Have you tried the other? 

If v10 works but v9.5 does not, I would suggest patching to v9.71.  If that doesn't work, then it was probably just broken and won't be fixed.   Upgrade to PSQL v10 (or even better v11).
