NAME

       ALTER DATABASE - change a database

SYNOPSIS

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

       where option can be:

           CONNECTION LIMIT connlimit

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

       ALTER DATABASE name RENAME TO newname

       ALTER DATABASE name OWNER TO new_owner

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  and  third 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.

       The fourth 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  fifth 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.)

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.

       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.

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

       newname
              The new name of the database.

       new_owner
              The new owner of the database.

NOTES

       It  is also possible to tie a session default to a specific user rather
       than to a database;  see  ALTER  USER  [alter_user(7)].   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.
