Yeah. That is CREATE FUNCTION ll_to_earth(float8, float8) RETURNS earth LANGUAGE SQL IMMUTABLE STRICT PARALLEL SAFE AS 'SELECT cube(cube(cube(earth()*cos(radians($1))*cos(radians($2))),earth()*cos(radians($1))*sin(radians($2))),earth()*sin(radians($1)))::earth'; which is problematic: the function calls are not schema-qualified and there's not a really easy way to fix that. There's work afoot to fix that [1], but it's not committed yet let alone in any shipping version. Nonetheless, your best bet for fixing this might be to install the earthdistance 1.2 files from the latest patchset in that thread. regards, tom lane [1] https://www.postgresql.org/message-id/flat/3395418.1618352794@xxxxxxxxxxxxx
