Ok. BTW Mr. Kataoka who is maintaing Japanese version of PostgreSQL

ODBC driver have found a bug in 6.3.2 pg_dump and have made patches.
I confirmed that the same bug still exists in the current source
tree. So I made up patches based on Kataoka's. Here are some
explanations.

o fmtId() returns pointer to a static memory in it. In the meantime
there is a line where is fmtId() called twice without saving the
first value returned by fmtId(). So second call to fmtId() will
break the first one.

o findTableByName() looks up a table by its name. if a table name
contanins upper letters or non ascii chars, fmtId() will returns
a name quoted in double quotes, which will not what findTableByName()
wants. The result is SEG fault.  -- Tatsuo Ishii t-ishii@sra.co.jp
