sql - Can a postgres function run alone without needing the client side to wait for a result? -


i know postgresql locks row while doing function because of transaction process. tried trigger function when last row of table unlock.

let's take example:

function_one() , function_two defined inside pg.

my application use function_one() add data or update stuff whatever. when it's done, last row needed unlock , can launch other transaction if want. @ point want postgresql launch function_two() when function_one() done.

thanks answer(s).

edit : more informations

i have tried put trigger on pg catalog did not work because had information needed view , can't trigger data of view.

so release lock need 1 of following commands:

commit; rollback;

so if had code so: 

function_one(); commit;     function_two();

that looking for. issue chaining functions in such way dictate when lock gets released.
