It's not clear what you're asking for. Could you please clarify?

Actually, "-test1" is a text argument that testme.exe should receive
from standard input. For example,
Executing testme.exe generates the following output,
Please select one of the following options:
1) test1
2) test2
3) exit
Please enter your option here:-test1 <-This -test1 is what user would

The psql command is probably linked against readline; did you look
in the ~/.psql_history file?

If you're using Python 2.4 you should look into the subprocess module.
I think these docs might be what you're looking

It looks like the process you start is blocking on
It depends mostly on how the spawned process handles conditions like
closed pipes, EOF, etc.
In general and on *nix, any spawned and terminated process will become
and remain a zombie until "reaped", i.e. until the final status is
collected by a calling os.waitpid().
To avoid zombies, you should

The process should receive an EOF. It will typically handle EOF by
terminating, but that is not guaranteed.
