The code in ATPostAlterTypeParse was very deeply indented, mostly because
there were two nested switch-case statements, which add a lot of
indentation. Use if-else blocks instead, to make the code less indented
and more readable.
This is in preparation for next patch that makes some actualy changes to
the function. These cosmetic parts have been separated to make it easier
to see the real changes in the other patch.
