Description:
------------
When using pcntl_fork with PHP the child processes are unable to use a database connection that has been created via PEAR DB to a postgresql DB server to update/insert any rows.

Reproduce code:
---------------
http://www.karlaustin.com/php/pcntl-db.phps

Expected result:
----------------
DB Should have updated values. It does not.

Actual result:
--------------
Error:

[nativecode=
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

This doesn't work, cause the parent kills the connection automatically via zend_list_delete when it ends.

I have tried creating a new connection (in the child) once the process has been forked, it will also not do an INSERT or UPDATE either, as the connection is created in the child, I would assume the parent should not close the connection? Yet it appears it does.

This doesn't seem to be a PEAR DB problem. Please test your code with the native functions and reopen this bug if you still feel that it's a PEAR DB related issue.
