If you have an extension that's marked not relocatable and drop it, its
schema is left behind; trying to create the extension again, *crash*.

$ cat /pgsql/install/master/share/extension/crash--1.sql 
grant usage on schema @extschema@ to public;


$ cat /pgsql/install/master/share/extension/crash.control 
comment = 'crash'
default_version = '1'
relocatable = false
superuser = true
schema = 'crash'

alvherre=# create extension crash;
CREATE EXTENSION
alvherre=# drop extension crash;
DROP EXTENSION
alvherre=# \dn

alvherre=# create extension crash;
el servidor ha cerrado la conexión inesperadamente       Probablemente se debe a que el servidor terminó de manera
anormal      antes o durante el procesamiento de la petición.
 
La conexión al servidor se ha perdido. Intentando reiniciar: con éxito.
