The other thing you have to worry about is whether the collations you
use sort the same on both systems ... if they don't, you'll have
effectively-corrupt indexes on text columns on the standby.
According to
https://wiki.postgresql.org/wiki/Locale_data_changes
you should be okay for rhel/centos 6 to 7 migration unless you
use de_DE locale. But I don't know how thorughly that's been
checked.
Using logical not physical replication might be safer.
