It didn't exist before either, but I don't think the error is what you
think. Please note the error message indicated it's looking for a
"directory" named posixrules, not the file.
The error seems to be due to this code:
if (canonname == NULL)
{
int result;
fullname[fullnamelen] = '/';
/* test above ensured this will fit: */
strcpy(fullname + fullnamelen + 1, name);
result = open(fullname, O_RDONLY | PG_BINARY, 0);
if (result >= 0)
return result;
/* If that didn't work, fall through to do it the hard way */
}
where we append the name, then try to open the file, but since the
file does not exist result is < 0 and we fall through to the for(;;)
loop and try to do scan_directory_ci() on the filename rather than the
directory.
On windows, where I also get the error, the stacktrace, as of
b58c433ef90b is as follows:

Perhaps we just need to put the NUL char back, to trim off the filename again:
/* If that didn't work, fall through to do it the hard way */
fullname[fullnamelen] = '\0';
but I've not yet looked into why the file is missing in the first place.
