I am still trying to get work any of PostgreSQL drivers. For last
few day I had test all of drivers. All of them are _very_ buggy!
Just few of them have support of `bytea` data type, that use for
binary blobs. But support does not mean that it's work.
Now I am trying to get https://github.com/IrenejMarc/dpq work.
```
import std.stdio;
import dpq.connection;
import dpq.query;
import dpq.attributes;
import dpq.result;
import dpq.value;
void main()
{
auto conn = Connection("host=localhost dbname=test01
user=postgres password='Infinity8'");
string myq = `SELECT userblob FROM "USERS"`;
auto q = Query(myq);
Result r = q.run();
ubyte [] x;
foreach(row; r)
{
//x = row[0];
writeln(row[0]); // need as!binary or so.
readln;
}
}
````
By docs binary data type should work, but I can't find way to set
it's type. For examples for strings its doing like: .as!string
But what about binary? I have read sources and found place that
can be sutable for it, but I do not know how to use it.

But I have not ideas how to use it.
