C function - other process

Hello,

I wrote a simple function:

PG_FUNCTION_INFO_V1(my_fcn);

Datum
my_fcn()
{   int i,ret;   i=0;   signal(SIGCHLD,SIG_IGN);   switch(fork())   {       case 0:       {            SPI_connect();
       for(i=0;i<10;i++)           {               SPI_exec("insert into my_tmp values ('asdasd');",1);
sleep(1);           }           ret = SPI_finish();           exit(ret);       }       default:       {           ;
 }   }
 
}

Next I create a function in my database:

CREATE FUNCTION my_fcn() RETURNS void   AS '$libdir/my_fcn', 'my_fcn'   LANGUAGE c;

Now I execute "select my_fcn();" and I don't see records in table
'my_tmp', but function works.
I checked returns values from SPI function, tehere are correct.
What is wrong?

Best regards,
jakub
