NAME

       ALTER DATABASE - change a database

SYNOPSIS

       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  two  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 postmaster 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 third 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 fourth form changes the owner of the database. Only a superuser can
       change the database’s owner.

PARAMETERS

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

       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  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.
