 Yes, I discovered this a few weeks ago. It looks like libxml is not

 annoying.

 Ugh! That is worse than a simple library link incompatibility.

Seems to me that Perl (?) is calling functions it is not supposed to call
- I'm guessing due to assumptions about mismatching lifecycles. The
parsing functions themselves are supposedly reentrant.

 IMHO, this is a job for the application.

Changing applications is several times more expensive and often simply not
possible.

Re: [HACKERS] VACUUM FULL out of memory

 Note that you should almost never use VACUUM FULL unless you've really
 messed things up.  I understand from the thread that you're just testing
 things out right now.  But VACUUM FULL is not something you should _ever_
 need in production, if you've set things up correctly.

Then why does it exist? Is it a historical leftover? If it is
only needed for emergency, should it not have a different name?
Just curious..
