libpq (C++) - Insert binary data

  Hi there,

I'm sitting for days now, and I can't get this to work:

I want to insert binary data (bytea) into my postgres DB via the c++ libpq.

What I have is a char* (actually a QByteArray) and I want to insert it
into the DB and the retrieve it from there again.

I can't find any good examples or tutorials online, so can anyone help
me (or direct met to a tutorial) on how to insert binary data and
retrieve it again?

Thank you very much
Christoph
