----------------------------+---------------------------
 Reporter:  Björn Harrtell  |      Owner:  pramsey
     Type:  defect          |     Status:  new
 Priority:  medium          |  Milestone:  PostGIS 3.2.0
Component:  postgis         |    Version:  master
 Keywords:                  |
----------------------------+---------------------------
 Reproduction:

 {{{
 drop table test;
 with vals(k, geom) as (values (1, 'POINT(1 1)'::geometry), (2, 'POINT(1
 2)'::geometry))
 select * into table test from vals;
 analyze test;
 select st_estimatedextent('test', 'geom');
 -- BOX(1 0.995000004768372,1 2.005000114440918)
 create index test_geom_idx on test using gist (geom);
 select st_estimatedextent('test', 'geom');
 -- BOX(1 1,1 2)
 drop index test_geom_idx;
 create index test_k_geom_idx on test using gist (k, geom);
 select st_estimatedextent('test', 'geom');
 -- BOX(1.401298464324817E-45 1,2.802596928649634E-45 1)
 }}}

 This is on:

 POSTGIS="3.2.0dev 3.2.0beta2-11-g27f44ecf6" [EXTENSION] PGSQL="120"
 GEOS="3.9.0-CAPI-1.16.2" PROJ="7.2.1" LIBXML="2.9.12" LIBJSON="0.15" (core
 procs from "3.2.0dev 3.2.0beta2-3-geda70258f" need upgrade)

 But I think it's an old bug.
