ALTER
NAME
  ALTER DATABASE - change a database

SYNOPSIS
  ALTER DATABASE name SET variable { TO | = } { value | DEFAULT }
  ALTER DATABASE name RESET variable

DESCRIPTION
  ALTER DATABASE is used to change the session default of a run-time
  configuration variable for a PostgreSQL database. Whenever a new session is
  subsequently started in that database, the specified value becomes the
  session default value.  The database-specific default overrides whatever
  setting is present in postgresql.conf or has been received from the
  postmaster.

  Only a superuser or the database owner can change the session defaults for
  a database.

  PARAMETERS

  name The name of the database whose session defaults are to be altered.

  variable

  value
       Set the session default for this database of the specified
       configuration variable to the given value. If value is DEFAULT or,
       equivalently, RESET is used, the database-specific variable setting is
       removed and the system-wide default setting will be inherited in new
       sessions. Use RESET ALL to clear all settings.

       See SET [set(5)] and the Administrator's Guide for more information
       about allowed variable names and values.

DIAGNOSTICS
  ALTER DATABASE
       Message returned if the alteration was successful.

  ERROR: database "dbname" does not exist
       Error message returned if the specified database is not known to the
       system.

NOTES
  Using ALTER USER [alter_user(5)], it is also possible to tie a session
  default to a specific user rather than a database. User-specific settings
  override database-specific ones if there is a conflict.

EXAMPLES
  To disable index scans by default in the database test:

  ALTER DATABASE test SET enable_indexscan TO off;

COMPATIBILITY
  The ALTER DATABASE statement is a PostgreSQL extension.

SEE ALSO
  ALTER USER [alter_user(5)], CREATE DATABASE [create_database(l)], DROP
  DATABASE [drop_database(l)], SET [set(l)]
