2.4 Adjusting checkpoints and xlogSo far, this chapter has provided insight into how PostgreSQL writes data, in general, what Xlog is used for. Given this knowledge, we can now continue and learn what we can do to make our databases work more efficiently in both replication and single-server operations.2.4.1 Understanding CheckpointsIn this chapter, we have seen that it has been written to Xlog before the data can be elsewhere. The problem is that if

PHP and Web pages use UTF-8 encoding, the database is SQL server2008, using the default encoding (936, which is GBK encoding) When reading the database data, use PHP's own json_encode () to return to the front end, the result Chinese is not displayed.

If you want to insert Chinese correctly into SQL Server 2008, add a code: $query = Iconv ("Utf-8", "Gbk//ignore", $query);//In ord
