The investigation of post-AGB objects (proto-planetary nebulae) is very
important from the standpoint of physical and chemical changes occurring during
the late stages of stellar evolution. The Toru\'n catalogue of Galactic
post-AGB and related objects is an evolutive catalogue containing astrometric,
photometric and spectroscopic data as well as HST images for all known post-AGB
objects and candidates in our Galaxy. This free-access catalogue can serve as
an ideal tool to study different groups of post-AGB objects, especially due to
the fact that all information is gathered in one place. The second release of
our catalogue introduces a simple classification scheme of post-AGB objects and
includes a significant number of new objects, photometric data, spectra and
images. Here, using objects from the catalogue we consider the problem of the
termination of the AGB phase.
