Re: BUG #13800: There is no UNLOAD command

Thanks for that explanation.=20

I need to restart the server because on Windows I can't overwrite the DLL w=
hile it is loaded. So I have to restart the server every time. And because =
of my paying customers I have to do coding on Windows.=20

Why would you need to restart?  Just starting a fresh connection ought to b=
e enough.

There's pretty much no chance UNLOAD will ever happen, so don't hold your b=
reath waiting.  We lack any defined method, for example, for extensions to =
disconnect from function hooks once they've inserted something in them.
(Reversing what was done at LOAD time wouldn't work, since it'd break any s=
ubsequent attachments to the same hook.)  Custom GUCs would be another big =
problem to reverse out, and if I'd consumed any caffeine yet today I could =
probably name several other trouble spots.  It's not insoluble, perhaps, bu=
t the amount of work required seems far out of proportion to the benefits.
