Don't forget that extensions are not just contrib or third party Open
Source software, but a lot of in-house code, mostly functions written in
SQL and PLpgSQL. In non-English speaking countries, the parameter names
and comments are typically not written in English.
When we're talking Japan they have some quite specifics needs and I came
to understand that the database encoding and the script encoding are not
to be the same, usually. So I still vote for handling this parameter.

The whole documentation needs to be:
<varlistentry> <term><replaceable class="parameter">encoding</replaceable></term> <listitem> <para>
The <literal>encoding</literal> in which the script file is read. </para> </listitem> </varlistentry>
The code to support that is on the order of 25 lines of code, once we
get rid of the SQL command level support for it.
