Subject: [PATCH] From: "Thomas G. Lockhart" <lockhart@alumni.caltech.edu>
For substr() and substring() on the text data type, the relevant code is in
varlena.c. You are right, there is a problem. I have a patch which I will
apply to the source tree soon. The copy enclosed below probably does not
preserve tabs correctly so cannot be applied directly; the relevant change
is simply changing the ">=" to ">"...
