The answer is "No" if you refer LongVarBinary to Delphi's field type. I want to associate :value2 with Delphi's
TBlobField.
If you refer LongVarBinary to the switches in pgsqlODBC, I have just tried switching on/off "Unknowns As LongVarChar"
and"Maximum/Longest" in "Unknown sizes" box. They all give me the same result that follows.
