escape_string_syntax

Hello,

I have a problem/question which might be already resolved in recent
versions of CLSQL.  I use CLSQL 4.0.3.1 together with Postgresql 8.3,
and observe that it emits the following messages (when putting
LaTeX-code in my database):

WARNING:  nonstandard use of \\ in a string literal
LINE 1: ...ITLE = 'Oktalsystem in Dezimalsystem 1',CONTENT = 'Sei $1023...
                                                             ^
HINT:  Use the escape string syntax for backslashes, e.g., E'\\'.

I have seen that I can disable this warning by setting 
  escape_string_warning = off
in "postgresql.conf".  However, this would not be optimal, because later
Postgresql versions might require the escaped syntax.  

Do more recent CLSQL-versions handle this better?  Or is there some trick
which makes CLSQL use the escape string syntax?

Thank you,
Nicolas
