System Configuration
---------------------
  Architecture (example: Intel Pentium)         : Intel PII

  Operating System (example: Linux 2.0.26 ELF)  : Linux 2.3.51

  PostgreSQL version (example: PostgreSQL-6.5.3):   PostgreSQL-6.5.3

  Compiler used (example:  gcc 2.8.0)           : egcs-2.91.66


Please enter a FULL description of your problem:

libpq++ leaks file descriptors and memory.

The constructor of PgConnection leaks a file everytime it is called.
Also DEBUG is on by default.

In addition the header file libpq++.H is insane. It contains
outdated copies of the header files (pglobject.h and the others).

The libpq++.H declares a smaller PgLargeObject (without class member
variables) then the PgLargeObject in pglobject.h.
This is the reason that examples/testlo crashes !

I fixed the header classes and memory/file leakage. I also added
header file PostgresDatabase.h which contains a new implementation
with exception handling, cursors and transactions. Look at
examples/testexcep.cc for the usage. The C++ interface is still
compatible with the old version.


Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
Running the next program, it crashes after approx. 1000 iterations
(depending on configuration of OS)


#include <libpq++.H>

#include <iostream>

int main()
{
  for (int i= 0; i < 10000; i++) {
    cerr << i << endl;
    PgConnection("");
  }
}


Running examples/testlo crashes with a damaged stack.


If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------

change 'FILE * debug' from a local var to a static var in
pgconnection.cc.

I added a tar containing a new version of the src/interfaces/libpq++
directory
because many files (source, headers, README, TODO, CHANGES) are
changed.
