After further review it seems like both of those things would be improvements, so here's a v2 that does it like that. This also adds a PG_USED_FOR_ASSERTS_ONLY marker whose lack was pointed out by the cfbot; no other meaningful changes. regards, tom lane From 9ff000246affd6b9063168a876bbcc0db4f78dd8 Mon Sep 17 00:00:00 2001 From: Tom Lane <tgl@sss.pgh.pa.us> Date: Fri, 7 Feb 2025 15:37:30 -0500 Subject: [PATCH v2 1/6] Break out xxx2yyy_opt_overflow APIs for more datetime conversions. 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 by btree_gin.
