Hmm ... some experimentation shows that 7.2 and 7.3 return a count in
the FETCH command tag, but no earlier or later version does.  It's clear
though that libpq expects FETCH to have a count, see PQcmdTuples().
So I'd have to say this is something we broke in 7.4 and nobody noticed
until now.  The culprit seems to be pquery.c, which is assuming that
PORTAL_UTIL_SELECT queries always return the default command tag.
