5:ALTER SYSTEM DISCONNECT SESSION '206,34158' IMMEDIATE;
8:ALTER SYSTEM DISCONNECT SESSION '211,154' IMMEDIATE;

SYNOPSIS

       ALTER TABLESPACE name RENAME TO newname

DESCRIPTION

       ALTER TABLESPACE changes the definition of a tablespace.

       You  must  own  the tablespace to use ALTER TABLESPACE.	To alter the owner, you must also be a direct or indirect member of the new owning
       role.  (Note that superusers have these privileges automatically.)

PARAMETERS

       name   The name of an existing tablespace.

       newname
	      The new name of the tablespace. The new name cannot begin with pg_, as such names are reserved for system tablespaces.

	      The new owner of the tablespace.

EXAMPLES

       Rename tablespace index_space to fast_raid:

       ALTER TABLESPACE index_space RENAME TO fast_raid;

       Change the owner of tablespace index_space:

       ALTER TABLESPACE index_space OWNER TO mary;

COMPATIBILITY

       There is no ALTER TABLESPACE statement in the SQL standard.
