zabbix 7.4 - function base36_decode(pg_catalog.varchar) does not exist

[rn3dcx]

New install Zabbix 7.4 on Debian.
When I run: cat /usr/share/zabbix/sql-scripts/postgresql/timescaledb/schema.sql | sudo -u zabbix psql zabbix

Next I see notification:

@Zabbix:~$ cat /usr/share/zabbix/sql-scripts/postgresql/timescaledb/schema.sql | sudo -u zabbix psql zabbix

Why does NOTIFICATION appear: function base36_decode(pg_catalog.varchar) does not exist ?
What am i doing wrong?

Do you have any ideas on how to fix this?
