I was rather thinking in using the good official postgre C API wrapped
inside our DAOS... it would spare us the dependency in another lib...
but hey, if this is good enough, we can give it a try.

The only thing I don't like in it is that it would probably make our
code too much "PGsql" based, since we already have the C++ wrapper
classes we will use them, but with the low level API we would wrap it
into some "smart" interface, that we could then reuse if we ever
decided to change to mySQL or Oracle or anything like it...

But, no problems, give it a try, give me some code on how it would be
used to write basic SELECT/INSERT/UPDATE applications and we'll
discuss it.

ORM is not needed at all, I mean, it would be "nice" but is not
*needed*, since most of our code won't even bother with the DBMS code.
