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();

}
