Forum OpenACS Q&A: Response to Notice: Found postgres7.2 incompatibility

I'm using PG 7.1.2 and have many instances of =NULL and = NULL in mods I've made in OpenACS 3.2.x. So before I upgrade to PG 7.2 and beyond, I'll need to change many scripts. But I wonder, why wasn't =NULL just left in the PG code as a (depreciated) but still usable alternative?

Is it worth pursuing with the PG dev group or is it apt to be a worthless exercise?
OR
"Hey Bob, Just start making those changes from = NULL to is Null." ?
