I don't think it's going to be a hugely important feature, but
I don't see a problem with creating a new option (-C seems
fine) which would have the same effect as if the arguments
were contatenated into a file which is then used with -f. IIRC
-c has some special characteristics which means it's probably
best not to try to extend it for this feature.
ok, I'll try to write patch.
I have a question. Can be -C option multiple?
The SQL is without problem, but what about \x command?
postgres=# \dt \dn select 10;
No relations found.
List of schemas
┌──────┬───────┐

\dn: extra argument "10;" ignored
I don't understand the question.
You should include one sql or psql command per -C option, ISTM. e.g.
psql -C '\dt' -C '\dn' -C 'select 10;'
Isn't that what we're talking about with this whole proposal?
cheers
