BUG #2295: MemoryContextSwitchTo missing

The following bug has been logged online:

Bug reference: 2295
Logged by: tomek
Email address: tomek(at)fullopcja(dot)hopto(dot)org
PostgreSQL version: 8.1.0.5309
Operating system: WIN XP
Description: MemoryContextSwitchTo missing
Details:

I was trying to install libpgxml addon with 8.1.0 distribution. Afer hours
of searching i've discovered that libxml is trying to call (or is linked) to
function MemoryContextSwitchTo witch should be in postgres.exe.

This function was in previous versions of postgres.exe (eg 8.0.3....).

Is it possible to implement-back this function in next release or rather we
should wait for new release of libpgxml?

regards
tom

Uh, I see MemoryContextSwitchTo in 8.1. I think the problem might be
that the function is not marked with DLLIMPORT for XP. Can someone try
that and see if it fixes it?

You need to recompile libpgxml, apparently.

It's never a good idea to try to use an add-on with a different major
version of Postgres than it was originally built for.

No, the problem is it's a macro (actually inline, but effectively a
macro) in 8.1.
