IIRC -c has some special characteristics which means it's probably best not to try to extend it for this feature.

hello,
Have you thought of how to support -1 along with -C ?

> handle the input as with -f
that is, -1 -C would be equivalent to -c

and
psql -1 -C "sql_1; sql_2;" -C "sql_3; sql_4;"

=> ?

BEGIN;
sql_1;
sql_2;
END;

BEGIN;
sql_3;
sql_4;
END;

thoughts ?

The same logic could be added to -f
although I see less advantages as with adding -C

psql -1 -f "file1, file2" -f "file3, file4"
