That's not going to help anybody unless we also provide a definition of
"implicit transaction", which is a bit far afield for that man page.

I did miss a bet in the proposed pipeline addendum, though.
I should have written

    ... However, there
    are a few DDL commands (such as <command>CREATE DATABASE</command>)
    that cannot be executed inside a transaction block.  If one of
    these is executed in a pipeline, it will, upon success, force an
    immediate commit to preserve database consistency.

That ties the info to our standard wording in the per-command man
pages.
