Thanks Martijn,
This is exactly what I am looking for. I'm wondering how easy it is to
sit on top of this backend. Does anybody have any stand alone sample
code? Is it a library that can be linked or do you need to produce a
modified version of the postgres server? Can it be used in shared
library form and if so will it support multiple processes using it on
the same machine?
----------------------
"Well, in the backend you can do things like open a btree index, setup
an ScanKey to indicate which values you want and then keep calling
getnext(). If you set your scankey to (col1 >= 'A') it will start at
'A' and go up from there... "
