I agree... but then they might also be surprised if psql -c
'something' works differently from psql -c 'something' -f /dev/null

runningscripts that are sensitive to environment, you're running with -X anyway; so maybe that's not that big of a
deal,as it's kind of an implied -X with multiple -c or -f commands. And if you really wanted it, we could add a flag
toexplicitly include .psqlrc (or the user could just specify -f path/to/psqlrc).
It's tempting to propose making .psqlrc apply only in interactive
mode, period. But that would be an incompatibility with previous
releases, and I'm not sure it's the behavior we want, either.
