In a nutshell: do not use the CHAR data type (neither in Oracle nor in Postgres)
Unless your application actively checks the data type name of columns in a table you can simply change the type of
thosecolumns to varchar (or text) and get rid of the annoying (but required) behaviour of the CHAR type.
To be honest, I am surprised this didn't show up in Oracle, as I think the CHAR behaviour there is the same as in
Postgres.
