I do not support this at all.  UTF8 is the future.  We support languages
which use charsets other than iso-8859-1/15.  By switching to utf8 we
can mix languages on the same page without a problem.  Keeping the lang
files in sync for both charsets is a lot of extra work and has the
potential to cause real problems.

We should look at fixing the UTF8 issues, not avoiding them.

What is the peformance trade off of the additional layer that you are
proposing here?  Have the tests been run on a range of data sets on both
mysql and pgsql?  Running the same test 3 times on pgsql with 1 data set
is hardly comprehensive testing and comparison.

34% is a big difference.  At the same time added flexibility of ADOdb,
not to mention that it is maintained are pretty big positives in my
book.
