As far as the changes in datetime.c and interval.c are concerned,
yes. I don't care too much about what you did in fe-print.c,
although TBH that case should be unreachable shouldn't it?
When would PQntuples() return -1?
(I shy gently away from the fact that that fe-print.c code is
relentlessly untranslatable.)
