Thread: Aggregate detoasted arguments lifetime
Dear pg-hackers, Making an aggregate I want to stuff all input values (detoasted) in an array and process them all togheter with finalfunc. This is because in order to process them a conversion is involved and I'm trying to reduce the number of conversions to the lowest possible. My question is: if I write in the "state" array pointers to DETOASTED input args, will I find them intact at finalfunc time ? TIA --strk;

You are called in a short-lived memory context. You could allocate query-lifetime memory in fcinfo->fn_mcxt, but it's then your responsibility to ensure there are no undesirable memory leaks. regards, tom lane
