[GENERAL] static variables in functions

[Gyozo Papp]

hello everyone,

is there any possibility to keep the value of an arbitrary type variable in a plpgsql 
function between its invocations?
If not, can it be made with functions written in C instead? I've "static storage" in 
my mind. 
Can it be made thread-safe?
