Previous commits invented timestamp2timestamptz_opt_overflow, date2timestamp_opt_overflow, and date2timestamptz_opt_overflow functions to perform non-error-throwing conversions between datetime types. This patch completes the set by adding timestamp2date_opt_overflow, timestamptz2date_opt_overflow, and timestamptz2timestamp_opt_overflow. In addition, adjust timestamp2timestamptz_opt_overflow so that it doesn't throw error if timestamp2tm fails, but treats that as an overflow case. The situation probably can't arise except with an invalid timestamp value, and I can't think of a way that that would happen except data corruption. However, it's pretty silly to have a function whose entire reason for existence is to not throw errors for out-of-range inputs nonetheless throw an error for out-of-range input. The new APIs are not used in this patch, but will be needed in upcoming btree_gin changes.
