Обсуждение: Vacuum in multi-statement

This used to work in 8.2:

psql postgres -c "VACUUM table1; SELECT now()"

But in cvs head it throws an error:
ERROR:  VACUUM cannot be executed from a function or multi-command string

This must be because of the recent changes to PreventTransactionChain.

Should we try to keep the old behavior for backwards-compatibility? The 
change will break some people's scripts, that's the way I noticed it.

That's intentional.  It "worked" only for rather small values of "work".
