Re: closing file in adjust_data_dir

Hi,

I was looking at the commit:

commit 2fe3bdbd691a5d11626308e7d660440be6c210c8

    Check return value of pclose() correctly

In src/bin/pg_ctl/pg_ctl.c :

    if (fd == NULL || fgets(filename, sizeof(filename), fd) == NULL || pclose(fd) != 0)

If the fgets() call doesn't return NULL, the pclose() would be skipped.

Since the original pclose() call was removed, wouldn't this lead to fd leaking ?

Please see attached patch for my proposal.

Cheers
