The functions for adding and updating dimensions have been refactored in C to: - improve usage of proper error codes - make messages that better conform with the PostgreSQL standard. - improve security by avoiding that lots of code run under SECURITY DEFINER A new if_not_exists option has also been added to add_dimension() and a the number of partitions can now be set using the new set_number_partitions() function. A bug in the validation of smallint time intervals has been fixed. The previous code didn't check for intervals > 0 and smallint intervals accepted values up to UINT16_MAX instead of INT16_MAX.
