I have Odoo Community source version installed, which shows an error when clicking on sequence. The error is listed below.

Initially I did not have such errors and had succefully set the sequence for Purchase Orders. Now I need to change the Sequence for Sales Order but I am unable to do it. 

When I accessed the database thru PGAdmin 4 I was able to change the Prefix and next increment number from the ir_sequence table. It changed the prefix but I am not able to change the next increment number.

I do not want to reinstall the Odoo and redo all the changes in the database. Please let me know whether the next increment number in the sequence(sales order) can be changed using PGadmin. 

https://github.com/odoo/odoo/issues/20269   This link also shows up such message received elsewhere who is using postgresl 10. I too have upgraded the database to Postgresql 10. Hope it is not causing such issue. Is it possible to downgrade if postgresql version is the issue.
