PostgreSQL的 initdb 源代码分析之十九

继续分析：

    setup_dictionary();

展开：

其中：

cmd 是："/home/pgsql/project/bin/postgres" --single -F -O -c search_path=pg_catalog -c exit_on_error=true -j template1 >/dev/null

dictionary_file 是：/home/pgsql/project/share/snowball_create.sql

/*
 * load extra dictionaries (Snowball stemmers)
 */
static void
setup_dictionary(void)
{
    PG_CMD_DECL;
    char      **line;
    char      **conv_lines;

    fputs(_("creating dictionaries ... "), stdout);
    fflush(stdout);

    /*
     * We use -j here to avoid backslashing stuff
     */
    snprintf(cmd, sizeof(cmd),
             "\"%s\" %s -j template1 >%s",
             backend_exec, backend_options,
             DEVNULL);

    PG_CMD_OPEN;

    conv_lines = readfile(dictionary_file);
    for (line = conv_lines; *line != NULL; line++)
    {
        PG_CMD_PUTS(*line);
        free(*line);
    }

    free(conv_lines);

    PG_CMD_CLOSE;

    check_ok();
