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.
