Oleg,

Thanks for your suggestion but I'm not sure how this will help. The
function is created _after_ the tsearch installation (script below). I'm
backing up on one machine and trying to restore to another. 

Cheers

Mike

Mike,

I think the problem is that tsearch2 is referenced by your SP (stored
procedure)
and your SP should be recreated *after* tsearch2 installed because
functions
are referenced by OID and your SP try to lookup tsearch2 functions
using old OID.
