Hi,
   I am trying to convert the pl/pgsql parser from Lex/Bison to AntLR, to
check whether it would make parsing will get simpler. Just to give some
background, pl/pgsql is a equivalent of PL/SQL in the open source database
postgresql. While i was trying that, there was Flex token, that has the
beginning of line as one of its condition. I couldn't find the equivalent in
AntLR and i raised the doubt in the forum. When i went ahead and checked it,
this one is un-documented option called "#option dump" where '#' has been
mentioned as a rule like this *^#option* in flex.
  So i really don't know, why it was decided to be at the beginning of line
and i failed trying to think of a reason.

Thanks,
Gokul
