From dd637597366a5a26ecf4f02737c9b9e3341c3e02 Mon Sep 17 00:00:00 2001 From: Alexandre Felipe Date: Wed, 11 Feb 2026 20:42:25 +0000 Subject: [PATCH 2/3] SLOPE Builtin support This adds slope information to several builtin functions. type casting, addition, subtraction, common mathematical functions, e.g. atan, sinh, log, exp, erf, etc. And some date manipulation function. This may not be complete, but already covers obvious cases. e.g. SELECT created_at::date, count(1) FROM tasks GROUP BY 1; can use an index on created_at, to count tasks per day. and much more. --- src/backend/utils/adt/misc.c | 88 ++++++ src/include/catalog/pg_proc.dat | 522 +++++++++++++++++++------------- 2 files changed, 396 insertions(+), 214 deletions(-) diff --git a/src/backend/utils/adt/misc.c b/src/backend/utils/adt/misc.c index 32a787d7df7..c9d4f56037f 100644 --- a/src/backend/utils/adt/misc.c +++ b/src/backend/utils/adt/misc.c @@ -32,6 +32,7 @@ #include "funcapi.h" #include "miscadmin.h" #include "nodes/miscnodes.h" +#include "nodes/supportnodes.h" #include "parser/parse_type.h" #include "parser/scansup.h" #include "pgstat.h" @@ -1093,3 +1094,90 @@ any_value_transfn(PG_FUNCTION_ARGS) { PG_RETURN_DATUM(PG_GETARG_DATUM(0)); } + +/* + * monotonic_slope_support + * Generic helper for prosupport functions that declare monotonic slopes. + * + * If the request is a SupportRequestMonotonic, fills in nslopes and slopes + * and returns the request pointer.
