Why Python has no equivalent of JDBC of Java?

Nope, it requires the instantclient and, on Linux only, also the
installclient-devel package. And a bunch of obscure and terrible settings,
like LD_LIBRARY_PATH...

Yes it's that the problem.
Well I love Postgres, but IMHO the big disadvantages over Oracle are two:
BLOBs and performance.

IMHO this is the more logical answer to my doubts.

It would surprise _me_. Oracle did not even uploaded ojdbc to the maven
repository...

I discovered it two years and an half ago, when I started to program in
Java too. Sorry if I didn't had the time to post but I'm working. And sorry
again, I don't know the whole basics of every programming language in the
world. I only programmed in Python 2 and 3, Cython, C, C++, Fortran, Qt,
PHP, Visual Basic .NET, LabView and  Javascript.

Well, it seems to me the majority of python db drivers uses Cython, Python
C API or external C libraries. So in this particular case Python *could* be
more performant than Java. I don't know, you should do some benchmark with
different queries, different in nature, complexity and number of rows
retrieved, on the same db, accessed once with Java and once with Python.
The problem is benchmarking Java not so easy as Python. It's very boring.
