More code cleanup.
PreparedStatement now releases resources
on .close(). (SF bug 553268)
Quoted identifiers not used if server version does not
support them. Also, if server started with
--ansi or
--sql-mode=ANSI_QUOTES,
‘"’ will be used as an
identifier quote character, otherwise
‘'’ will be used.
ResultSet.getDouble() now uses code built
into JDK to be more precise (but slower).
LogicalHandle.isClosed() calls through to
physical connection.
Added SQL profiling (to STDERR). Set
profileSql=true in your JDBC URL. See
README for more information.
Fixed typo for relaxAutoCommit parameter.
