After some deeper investigation I found an old bug in Orafce :-/. I am
sorry for the noise.
This old bug is related to introduction aliases types of varchar -
nvarchar2 and varchar2. In this age the "in" function can use a
protransform column, but there was not a possibility how to set this column
externally, and Orafce used dirty update. The value was correct, but the
new dependency was not used. Originally it was not a problem, because the
transform function was built in. But there was a new issue related to
Postgres 12 when these functions were renamed. I fixed this issue by
introducing my own wrapping function - but without dependency I broke the
binary upgrade.
On Postgres 12 and higher I can use ALTER FUNCTION SUPPORT and all works
well. On older platforms I have to hack pg_depend, but it is working too.
Again I am sorry for false alarm
