Bug reference:      16534
Logged by:          Martin Winkel
Email address:      martin@tiogatours.nl
PostgreSQL version: 12.3
Operating system:   Windows 10 x64 / Ubuntun 20.04 x64
Description:

I have indexes on on the latitude() and longitude() values of an
earth-column. I can analyze these tables, but autoanalyze fails. Because
autoanalyze fails, it will keep trying to analyze these tables.

I created a test-script. After this script, check the postgresql log, you
will find the error attachted below.

TEST SCRIPT:

CREATE EXTENSION cube;
CREATE EXTENSION earthdistance;
    
CREATE TABLE earthdisttest
(
    id serial NOT NULL,
    gps earth NOT NULL,
    PRIMARY KEY (id)
);
    
CREATE INDEX idx_earthtest
    ON earthdisttest USING btree
    (latitude(gps) NULLS LAST);
    
    
ALTER TABLE earthdisttest SET (autovacuum_vacuum_scale_factor = 0.0);
ALTER TABLE earthdisttest SET (autovacuum_vacuum_threshold = 3);
ALTER TABLE earthdisttest SET (autovacuum_analyze_scale_factor = 0.0);
ALTER TABLE earthdisttest SET (autovacuum_analyze_threshold = 3);

INSERT INTO earthdisttest (gps) VALUES (ll_to_earth(10,30)),
(ll_to_earth(1,59)), (ll_to_earth(43,12)), (ll_to_earth(-10,23));
