> As for now HAWQ sends filter string without datatypes and length:
> a<column index>c<constant value>o<operation code>...
> Idea is to send filter in following format:
> a<column index>c<scalar constant datatype oid>s<number of characters to read>d<actual data>o<operation code>
> or 
> c<scalar constant datatype oid>s<number of characters to read>d<actual data>a<column index>o<operation code>
> This approach takes care of escaping symbols.
