This doesn't work because '\' is turned into '\\' by PostgreSQL, and

Something like this might be better:

    my $arg = shift;
    $arg =~ s!\\(?:\\|(\d{3}))!$1 ? chr(oct($1)) : "\\"!ge;

You need to do this in one go because pre-escaped backslashes like
like '\\101' cause problems otherwise.

(All ''-delimited strings in this posting use strict SQL syntax,
i.e. no escaped backslashes.)


I think you're right, although that's rather ugly ;-) I'll commit this change for now, but if anyone comes up with a simpler recipe I'll be happy.

Also, it looks to me like I missed escaping \ on the way back, which I will fix.

cheers
