Hi people,
Are any of you lot handy with pgtcl then? Or should I be posting on
another list, the only other list I could possible see was
pgsql-hackers?
I managed to modify the tcl script at the address I posted below to
save the field I wanted it to. However I've still not managed to get
it to save the names and values of all my primary keys. All I've
managed to do is create a script that does nothing.
I've attached it, could someone help?
Thanks
Glyn
