"{ OJ " group outer joins in queries from OpenOffice.org?

Hi,

This was discussed on the pgsql-sql list. Tom Lane asked if someone knows
about this, no answer at that list, so I guess I'll ask here:

OpeoOffice adds "{ OJ " .., "}" around outer joins. Apparently, as Tom
recalls, the ODBC standard expects this, since ODBC rephrases the query to
be compatible with different db servers. I don't think this construct
exists in JDBC? Anyone knows?

Two bug reports on OO.org with the same matter, only seem to involve
postgresql jdbc driver?
