To quote the 8.0 release notes:

: Observe the following incompatibilities:
: ...
: Nondeferred AFTER triggers are now fired immediately after completion of
: the triggering query, rather than upon finishing the current interactive
: command. This makes a difference when the triggering query occurred
: within a function: the trigger is invoked before the function proceeds
: to its next operation.

This change is not going to be back-patched into 7.x, because it would
break applications that depended on the old behavior.
