For some reason I see when I just have 
a command  like this it doesnt' have a grant connect on database
~/soft/pgsql_install/bin/pg_dump -U skoposov -h localhost -n xx  --no-tablespaces test1
but when I add  '-Fc' flag to pg_dump, I can see 'grant connect' inside the output (interdispersed with binary stuff)

I don't get it
