Thank you for picking up this task.

How about:

then packages which are required to build
<productname>PostgreSQL</productname> are missing.
See <xref linkend="install-requirements"/> for a list of requirements.

This change does not make much sense, given that you leave the
second part of the sentence.

Dunno if this change improves the wording, or the understanding.
How about replacing "site" with "installation"?

The part about "truncate" is correct, maybe you can include NAMEDATALEN
here as well.

The part about the first character is correct - except you quote the name.
Then any name is allowed. If you rewrite this part, maybe include this
as well.

The other changes look good.
