BUG and FIX: getTables - SYSTEM TABLE

In getTables in DatabaseMetaData.java it looks like
"TABLE" is returned as the TABLE_TYPE even if the
table is a SYSTEM TABLE.  It looks like the
getTableTypes code is working correctly - if SYSTEM
TABLE is not requested then none are returned.

The problem appears to be in
   case (byte) 'r':
       relKind = "TABLE";
       break;
which kind of forgets that sometimes an 'r' means a
TABLE and other times a SYSTEM TABLE depending on
TABLE_NAME.

the fix would be something like
   case (byte) 'r':
      if (relname.r.getBytes(1).startsWith("pg_"))
         relKind = "SYSTEM TABLE"
      else
         relKind = "TABLE";
      break;

For what its worth I am new to this list - I tried
searching the archive for this bug and was not able to
read the archive.  Hopefully this bug and fix have
already been posted - but if not...
