I'm sorry if I was unclear, I initially got the error using the JDBC-driver
which issues the commands:
java.sql.ResultSet acRset =
ExecSQL("set client_encoding = 'UNICODE'; show autocommit");

//set encoding to be unicode
encoding = Encoding.getEncoding("UNICODE", null);

if (!acRset.next())
{
throw new PSQLException("postgresql.con.failed", "failed getting
autocommit status");
}

in AbstractJdbc1Connection.openConnection()

I had to recompile the JDBC-drivers with the method changed to
"set client_encoding = 'LATIN1'", as my database is as you guessed created
with "createdb -E LATIN1 dbname"

Then I realised I could reproduse it from the psql cmd-line, and posted the
error I got from there. Sorry for the confusion.

But my question still stands, why does this work on Linux and not Solaris8?
The docs say PostgreSQL can convert to and from LATIN1<->UNICODE as long as
multibyte support is enabled, which it is default in 7.3.
