Comment (by robe):

 Where does this plvdate.version() function come from.

 I tried to replicate with:


 {{{
 CREATE SCHEMA IF NOT EXISTS plvdate;
 CREATE OR REPLACE FUNCTION plvdate.version() returns text AS
 $$ SELECT 'PostgreSQL PLVdate, version 3.7, October 2018'$$
 language sql ;

 SELECT box2d_in(plvdate.version()::cstring);
 }}}

 But it doesn't crash, just gives:

 {{{
 ERROR:  box2d parser - couldn't parse.  It should look like: BOX(xmin
 ymin,xmax ymax)
 }}}
