This statement didn't work in any version of PostgreSQL.

I'm guessing that the statement really was:
   UPDATE tu02t00 SET tu02pfusua = 'D\'AGOSTINO'
(notice the backslash).

That would have worked in PostgreSQL 9.0 with default configuration
(and given you a warning), but won't work with PostgreSQL 9.2.

If that is your problem, you can set standard_confirming_strings = off
to restore the old behaviour.

It would be much better, though, to adapt your program to use
standard conforming strings, like this:
   UPDATE tu02t00 SET tu02pfusua = 'D''AGOSTINO'
