In the case of manual installation (for the case where the source code is compiled for PG or the decompressed version is installed for PG), PG does not start automatically when it is started, and stops automatically when it is turned off, as a DBA, this is obviously unacceptable.

In Windows, you can use the pg_ctl command to generate the postgresql service and enable it to start itself. In fact, the installation v

NoSQLIt is a broad definition of non-relational data storage. It broke the long-term unification of the relational database and acid theory. Nosql data storage does not require a fixed table structure and usually does not have connection operations. It has incomparable performance advantages over relational databases in terms of big data access. This term was widely recognized in the early 2009 S.

After at least 4 years of intense debate, it is time to make a phased conclusion about the status quo of NoSQL. So many things have happened around NoSQL that it is difficult to make a simple generalization, and it is difficult to judge what it achieves and what it does not expect.
In many areas, NoSQL has not only been successful in the academic field but also
