I want to ask about how much "inserts" can I insert between BEGIN and END; When I do it last time ( I want to add about 1000 "inserts") - I get error - that buffer can contain to 20 000 characters. I use psql, so I'm not sure if this is a limit of psql itself or limit of backend. And may be anybody knows if it is possible change this limit and where?
