NAME

       ALTER DATABASE - change a database

SYNOPSIS

       ALTER DATABASE name [ [ WITH ] option [ ... ] ]

       where option can be:

           CONNECTION LIMIT connlimit

       ALTER DATABASE name RENAME TO newname

       ALTER DATABASE name OWNER TO new_owner

       ALTER DATABASE name SET TABLESPACE new_tablespace

       ALTER DATABASE name SET configuration_parameter { TO | = } { value | DEFAULT }
       ALTER DATABASE name SET configuration_parameter FROM CURRENT
       ALTER DATABASE name RESET configuration_parameter
       ALTER DATABASE name RESET ALL

DESCRIPTION

       ALTER DATABASE changes the attributes of a database.

       The  first  form  changes certain per-database settings. (See below for details.) Only the
       database owner or a superuser can change these settings.

       The second form changes the name of the database. Only the database owner or  a  superuser
       can  rename  a  database;  non-superuser owners must also have the CREATEDB privilege. The
       current database cannot be renamed. (Connect to a different database if  you  need  to  do
       that.)

       The  third  form  changes the owner of the database.  To alter the owner, you must own the
       database and also be a direct or indirect member of the new owning role, and you must have
       the CREATEDB privilege.  (Note that superusers have all these privileges automatically.)

       The  fourth  form changes the default tablespace of the database.  Only the database owner
       or a superuser can do this; you must also have create privilege for  the  new  tablespace.
       This  command  physically  moves  any  tables  or  indexes  in  the database's old default
       tablespace to the new tablespace. Note that tables and indexes in non-default  tablespaces
       are not affected.

       The remaining forms change the session default for 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
       postgres  command  line.  Only  the  database  owner or a superuser can change the session
       defaults for a database. Certain variables cannot be set this way, or can only be set by a
       superuser.

PARAMETERS

       name   The name of the database whose attributes are to be altered.

       connlimit
              How many concurrent connections can be made to this database. -1 means no limit.

       newname
              The new name of the database.

       new_owner
              The new owner of the database.

       new_tablespace
              The new default tablespace of the database.

       configuration_parameter

       value  Set  this  database's  session default for the specified configuration parameter to
              the given value. If value is DEFAULT or, equivalently, RESET is used, the database-
              specific  setting  is removed, so the system-wide default setting will be inherited
              in new sessions. Use RESET ALL to clear all database-specific settings.   SET  FROM
              CURRENT saves the session's current value of the parameter as the database-specific
              value.

              See SET [set(7)] and in  the  documentation  for  more  information  about  allowed
              parameter names and values.

NOTES

       It is also possible to tie a session default to a specific role rather than to a database;
       see ALTER ROLE [alter_role(7)].  Role-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.
