ALTER
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(5)] 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(5)]. 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.
