Isn't that habit outright wrong? ISTM that with the && in there,
what you're doing is equivalent to
PGOPTIONS=whatever
pg_restore ...
This syntax will set PGOPTIONS for the remainder of the shell session,
causing it to also affect (say) a subsequent psql invocation. Which is
exactly not what is wanted.
