ALTER USER name SET configuration_parameter { TO | = } { value | DEFAULT }
ALTER USER name SET configuration_parameter FROM CURRENT
ALTER USER name RESET configuration_parameter
configuration_parameter value
Set this role's session default for the specified configuration parameter to the given value. If value is DEFAULT or, equivalently, RESET is used, the role-specific variable setting is removed, so the role will inherit the system-wide default setting in new sessions. Use RESET ALL to clear all role-specific settings. SET FROM CURRENT saves the session's current value of the parameter as the role-specific value. If IN DATABASE is specified, the configuration parameter is set or removed for the given role and database only.
Role-specific variable settings take effect only at login; SET ROLE and SET SESSION AUTHORIZATION do not process role-specific variable settings.
See SET and Chapter 18 for more information about allowed parameter names and values.

There is no such thing in PostgreSQL.
You can limit the storage a user can use by keeping his data in a table space with a certain size.
