我在商情高级搜索中输入关键词后总是显示"没有数据" 有时候页首显示以下代码: Warning: pg_query() [function.pg-query]: Query failed: ERROR: could not open relation 1402009/1402047/1402048: Read-only file system CONTEXT: SQL statement "select oid from public.pg_ts_dict where dict_name = $1" PL/pgSQL function "tzh_search_ids" line 63 at assignment in /var/tradesns_svn/tradesns/src/api/BusinessInfo/BusinessInfo.php on line 264 Warning: pg_fetch_row() expects parameter 1 to be resource, boolean given in /var/tradesns_svn/tradesns/src/api/BusinessInfo/BusinessInfo.php on line 265 这到底是怎么回事啊? 大家帮帮忙啊!
