pg_autovacuum on Windows triggers string warning

Hi,

I have the postgresql.conf escape_string_warning active on my Win32 machine.  I have a couple databases on it which are
static. When pg_autovacuum checks these static databases it is triggering the warning: "non standard use of \\ in a
stringliteral at character 128 or character 355" depending upon which database it is checking. 

Maybe it can be "fixed" in 8.2 if it hasn't been addressed already.

Mike
