I want to execute for each row this command.
It is possible?

I supose you mean execute the command contained in each row. Anyway,
it is easy with a procedure, look for example at

https://www.postgresql.org/docs/10/static/plpgsql-statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN

just do a loop on your command table, follow the examples and you
should be done.
