Change template1 encoding

When people start to work with PostgreSQL, especially when they are used to Oracle, some things might be very confusing. A few of the questions we usually get asked are:. That makes three databases by default. Why does PostgreSQL need three by default? Lets see ….

Ok, this is the first point to remember: You can not drop a database which users are currently connected to in this case it is my own connection. Does it matter? Not really from a PostgreSQL perspective but probably all your clients pgadmin, monitoring scripts, … will have a problem now:. Now that this database does not exist anymore you can not longer connect if you do not provide a database name in you connection request. What happened? This brings us to the next question: When we create a new database what or who defines the initial contents?

If the above statement is true every new database created with the above syntax should contain the table and the extension, right? Ok, I got it, but what is template0 for then? You can only delete a database when there are no connections. But: You can only create a database from another database if there are no connections to the source, too.

Why then can I create a new database when I am connected to template1 when template1 is the source for the new database?

Yes, this is possible if you slightly adjust the syntax.

Fourth point to remember: For creating new databases you can use whatever database you like as the source when you specify then template explicitly. Fifth point to remember: When you want to drop a database or when you want to create a database there must be no connections to the database you either want to drop or you want to create a new database from.

How can I change "Encoding" on Explorer 9?

Because template0 is meant as the default unmodifiable database. You never should make any changes there. In a brand new PostgreSQL instance template0 and template1 are exactly the same. But why do I need both of them then? Assume you messed up template1 somehow installed too many objects, for example. Using template one you still can recover from that easily:.Too bad I found this after having lost my voice Kudos, nonetheless.

From my perspective hammering down lines makes the syntax and contextual logic sink in better. Thank you so so much, I am new to rails and db's and nearly broke google over a full day trying to resolve this.

change template1 encoding

After going through the steps, I have template1 with UTF8, not template? Dude, God bless you! Thanks you're amazing. I needed to do that too on Postgresql 9.

It's missnamed, though? You are actually changing template1, which is what is needed. Worked like a charm, thanks! Great help, very much appreciate it!

Yet another thanks :.By default, it copies the standard system database named template1. Thus that database is the "template" from which new databases are made.

If you add objects to template1these objects will be copied into subsequently created user databases. This behavior allows site-local modifications to the standard set of objects in databases. There is a second standard system database named template0.

This database contains the same data as the initial contents of template1that is, only the standard objects predefined by your version of PostgreSQL. Another common reason for copying template0 instead of template1 is that new encoding and locale settings can be specified when copying template0whereas a copy of template1 must use the same settings it does. This is because template1 might contain encoding-specific or locale-specific data, while template0 is known not to.

The principal limitation is that no other sessions can be connected to the source database while it is being copied. If this flag is set, the database can be cloned by any user with CREATEDB privileges; if it is not set, only superusers and the owner of the database can clone it.

If datallowconn is false, then no new connections to that database will be allowed but existing sessions are not terminated simply by setting the flag false. For example, one could drop template1 and recreate it from template0 without any ill effects. This course of action might be advisable if one has carelessly added a bunch of junk in template1. The postgres database is also created when a database cluster is initialized.

This database is meant as a default database for users and applications to connect to.

If the locale is C or equivalently POSIXthen all encodings are allowed, but for other locale settings there is only one encoding that will work properly. On Windows, however, UTF-8 encoding can be used with any locale. The encoding and locale settings must match those of the template database, except when template0 is used as template. Copying such data would result in a database that is corrupt according to the new settings.

Also, the limit is not enforced against superusers or background worker processes. To create a database sales owned by user salesapp with a default tablespace of salesspace :.

In previous versions of Postgresql, template0 had no predefined encoding, so that command gave no errors. You must pass a locale that matches your desired encoding and is supported by the host as well.
