Please note, that in PostgreSQL unquoted names are always folded to lower case:
https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
To enclose all the identifier names in quotes in target scripts you need to set the option “Quote identifiers=Always”, the way it is done on the screenshot:

After that save the changes and run the conversion. Also take a note that since you use this option, you should use the object names in double quotes in PostgreSQL.
