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 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   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.

       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.
