ALTER DATABASE(7)			   SQL Commands 			ALTER DATABASE(7)

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  data-
       base,  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  data-
	      base-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(7)] 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(7)], it is also possible to tie a session default to a spe-
       cific 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.
