Re: Help with restoring database from old version of PostgreSQL

You say that you just installed PG17. That's perfectly fine. If pgAdmin4
version 8.12 is recent, then it's fine to use that, too.

The thing is that sql files are just... a bunch of SQL statements.
Whatever SQL is generated by v9.6 will be easily processed by a modern
version.
