My main concern is identifying this issue by PosgtreSQL developers so it
can be addressed as some point in the future. I believe that is done now
and the issue is identified.

As it happens the sql in question is part of a common generic sql script
file where the same script file is run against 10+ different DBMSs to
update the database data from a previous release (all 10+ DBMS schemas
have the same table/column names, logical structure, logical data types,
etc). Having said that, I can introduce a PG-only data update file as a
workaround for PG in this case but not without complicating things quite
a bit. However, due to limited time and schedule, I will be just
accepting the error (based on cost-analysis of the error) in this case.

Best regards,
Farid
