I have been trying to execute a shell command from within postgresql
My C Function
#include <stdlib.h>
#include<postgres.h>
void shell_exec(text arg)
{
system(arg.vl_dat);
}
The function in postgres
CREATE FUNCTION xp_shellexec(text) RETURNS void
AS '/home/psql/cfuncs/shellexec', 'shell_exec'
LANGUAGE C STRICT;
Then run SELECT xp_shellexec(‘mkdir /home/psql/testing’)
No error message, it runs, but the directory isn’t created.
The C function works if I compile it, and run myself from the shell,
And I even just tried doing this:
void shell_exec(text arg)
{
system(“mkdir /home/psql/testing”);
}
and it still didn’t work…
the directory has rwx permissions for everyone
I am running freebsd 5.1, and the most recent version of postgres
Can someone give me some help?
Thanks
