I can't use psql variable in the DO command. Is it intentional behavior?

yes. psql variables living on client side, and are not accessible from server side . DO command is executed on server side.

But SELECT command also executed on a server side ))
I thought that the command is sent to the server after variable's replacement.


you can copy psql variables to GUC variables by set_config function, and then on server side use current_setting function for getting the content.
Yes, I know about workarounds.
