First of all, you should aware that SHIFT_JIS_2004 is a comppletely
different beast from SJIS. If you want to continue to use SJIS data in
7.4, you must use SJIS, not SHIFT_JIS_2004 on 8.3. Or do you have any
particular reason to use SHIFT_JIS_2004?
BTW,
> ERROR: character 0xe9ab99 of encoding "UTF8" has no equivalent in "SJIS"
I don't see this error message with PostgreSQL 8.3.0 running on a
Linux box. I can store UTF-8 0xe9ab99 (== U+9AD9) and retrieve it from
the SJIS client side (0xe9ab99 corresponds to 0xfbfc). Actually we can
confirm this by looking at line 6914 in
src/backend/utils/mb/Unicode/utf8_to_sjis.map:
{0xe9ab99, 0xfbfc},
Note that the left is the value for UTF-8, and the right side the
value for SJIS. I recommend you to double check your PostgreSQL 8.3
installation.
For your convenience, I have attatched a dump containing a table
(called "t1") which has the UTF-8 character in question.
$ createdb -E UTF_8 test
$ gunzip -c /tmp/t1.dump.gz|psql test
$ psql -c "set client_encoding to SJIS;select * from t1" test
