Обсуждение: database instance creation

Dear All,

 In Mysql, If we create a directory under mysql/data, mysql treated as database instance without starting mysql server.
 Is there any similar provision in postgres where we can create a database instance without starting postgresql server.

No, unfortunately there isn't (that would never work, but in theory we could have some attach/detatch command that would do it but there is no such thing). You can do a dump/reload of a single database, but that's the only thing...

Well, the Postgres program initdb is used to create a database instance;
it does not automatically start a server against it.  That sounds like
that might be a similar provision.
