[Minor] Improve reading in "1.2 Architectural Fundamentals " tutorial

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/18/tutorial-arch.html
Description:

Where it says:
"As is typical of client/server applications, the client and the server can
be on different hosts. In that case they communicate over a TCP/IP network
connection. You should keep this in mind, because the files that can be
accessed on a client machine might not be accessible **(or might only be
accessible using a different file name)** on the database server machine."

The distinction "(or might only be accessible using a different file name)"
does not add to the concept and degrades reading. I propose to remove it:
"As is typical of client/server applications, the client and the server can
be on different hosts. In that case they communicate over a TCP/IP network
connection. You should keep this in mind, because the files that can be
accessed on a client machine might not be accessible on the database server
machine."

Thanks!
