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 ┌──────┬───────┐ │ Name │ Owner │ ╞══════╪═══════╡ └──────┴───────┘ (0 rows) \dn: extra argument "10;" ignored some like psql -C "\dt \dn" -C "select 10" It is looking better than psql -c "\dt \dn \n select 10" Regards Pavel > > Pavel > > >> >> cheers >> >> andrew >> > >
