	fd = open(core_pattern_path, O_RDONLY | PG_BINARY);
	if (fd < 0)
	{
	ereport(LOG, (errcode_for_file_access(),
	errmsg("could not open file \"%s\".", core_pattern_path)));

	}

When viewing code i found possible handle leak on 932.
If the read function returns -1 on error, then close(fd) is not called before return false, which can cause a file descriptor leak.
