Hello Tom,
Thanks for the information. Here are the extensions we are using:
uuid-ossp
pgcrypto
citext
btree_gin
The warnings did start emitting shortly after the installation of btree_gin, so it seems somewhat suspect

I don't see that here, so I'm guessing it's coming from some extension.
What extensions do you have loaded?
Node type 110 would be T_SubscriptingRef in v12, which is a type name
that didn't exist in earlier versions (it used to be called ArrayRef),
so it's not very hard to believe that some extension missed out
support for that type. But the only core-PG suspect is
pg_stat_statements, and I can see that it does know that node type.
