Adrian, Christoph, Tom,
We identified as the problem being persistent on all tables with many records ( +600K ) and they all had a JSONB column ( we feel that might be related )
Luckily we were able to downgraded to version 11.6 with the same system MacOS 10.14.6 so that the OS impact can ruled out.
We will keep the 12.1 in place so that we can run additional tests to assist to pin-point the issue.
Feel free to ask but allow us to recover from these hectic days ;-)
Many thanks for the help !

Hi,
We have just upgraded our Postgres 9.6 database to 12.1 (pg_dumpall -> pg_restore on a clean installation) and now we are having some issues with one of our tables.
When we do the following statement:
SELECT * FROM f_gsxws_schedule WHERE UPPER(gwsc_dossier) = 'TEST'
the Postgres service restarts.
It seems that using UPPER() in the WHERE clause is causing this. The same statement without UPPER() works just fine.
I have tried to emulate the issue with other tables, but f_gsxws_schedule seems to be the only one.
The table also has another character field that is indexed, and the same problem occurs there. Whenever we use UPPER() or LOWER() to do a case-insensitive search, the service reboots.
Looking at the table's definition, I don't see anything different with the other tables.
Here is what is logged:

Has anyone noticed anything like this before? Any idea how to fix this?
