The problem is there in the error message - it is missing an assembly "Npgsql" (or rather a file Npgsql.dll). This is a dependency of the assembly you are using for your calls and needs to be present either in the same folder as the original assembly, a sub-folder of the LabVIEW project (or the LabVIEW Program Files path if you aren't using a project but you really should be) or the GAC. I suggest the first option.
