I have to do an out-of-place Postgres migration from PG12 to PG16 using:

 

pg_dump -F p -f dump.sql …

sed -i "s/old_name/new_name/g"

psql -f dump.sql …

 

Both databases are on UTF-8.

 

I wonder if there could be character set conversion errors here, as the data is temporarily written to a plain text file.

 

Why must it be a plain text dump instead of a custom or directory dump?  Restoring to a new (and differently-named( database is perfectly doable.

Because I can simply change the application from the old to the new structure then.
