ok,
thanks i will look into walbuffers
asynchronous_commit=off is a doubt for responsive environment (pg manual). for ex.
would it help if,
a game player , has to perform next move on basis of his/her previous move plus other players move.
all is sent to table and for each player a particular set is retrieved with a minimalistic data portfolio
