POSTGRESQL CREATE DATABASE ON LINUX FULL

The character set encoding specified for the new database must be compatible with the chosen locale settings ( LC_COLLATE and LC_CTYPE). CREATE DATABASE will fail if any other connection exists when it starts otherwise, new connections to the template database are locked out until CREATE DATABASE completes. The principal limitation is that no other sessions can be connected to the template database while it is being copied. The program createdb is a wrapper program around this command, provided for convenience.ĭatabase-level configuration parameters (set via ALTER DATABASE) and database-level permissions (set via GRANT) are not copied from the template database.Īlthough it is possible to copy a database other than template1 by specifying its name as the template, this is not (yet) intended as a general-purpose “ COPY DATABASE” facility.

Optional parameters can be written in any order, not only the order illustrated above.ĬREATE DATABASE cannot be executed inside a transaction block.Įrrors along the line of “ could not initialize database directory” are most likely related to insufficient permissions on the data directory, a full disk, or other file system problems. If true, then this database can be cloned by any user with CREATEDB privileges if false (the default), then only superusers or the owner of the database can clone it. How many concurrent connections can be made to this database.

The default is true, allowing connections (except as restricted by other mechanisms, such as GRANT/ REVOKE CONNECT). If false then no one can connect to this database. See CREATE TABLESPACE for more information. This tablespace will be the default tablespace used for objects created in this database. The name of the tablespace that will be associated with the new database, or DEFAULT to use the template database's tablespace. The default is to use the character classification of the template database. This affects the categorization of characters, e.g., lower, upper and digit. lc_ctypeĬharacter classification ( LC_CTYPE) to use in the new database.

The default is to use the collation order of the template database. This affects the sort order applied to strings, e.g., in queries with ORDER BY, as well as the order used in indexes on text columns. lc_collateĬollation order ( LC_COLLATE) to use in the new database. If you want to make them the default for a specific database, you can use ALTER DATABASE. The other locale settings lc_messages, lc_monetary, lc_numeric, and lc_time are not fixed per database and are not set by this command.
