Everything was a clean install ( MacOS Mojave and Postgres )
Export and import were done with the latest version of PGAdmin.
Please advise if we can provide you with anything ( logging etc . . . )
Is there a possibility to downgrade to version 11 ?
We upgraded over the weekend because we experienced a crash on our production server with “toast” issues as result.
Thanks in advance,
Marc

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?
Was the upgrade on the same machine?
Or was the machine also upgraded/updated?
I ask as there have been similar reports having to with changes in glibc version affecting collation.
