Re: executing SELECT xmlelement(name foo); causes "server closed the connection unexpectedly" Error

Here is an update.

the 8.3 version is now working after i reinstalled the OS.

most probably the issue was due to corrupt libxml2.

Thank you so much for all the help to get rid off the issue.

Your problem appears to be here.  Check you libxml installation.  Maybe 
someone forgot to export this symbol.   

I think it most likely is a corrupted download.  Red Hat's normal
release process includes checks for ABI breakage such as disappearing
symbols, so it's hard to believe there's really a problem of that ilk.

The annoying thing about this from a Postgres standpoint is that the
missing symbol results in a runtime crash; a failure at server startup
would be a lot better IMHO.  Ideally, shared libraries would be
processed with the equivalent of dlopen(RTLD_NOW).  But as far as I
can find we can't easily force that on Linux --- the only available
way to determine it is to set a magic environment variable that the
linker consults.

I could fix this in the RPM distribution by putting export LD_BIND_NOW=1
into the postmaster start script, but I wonder whether there's a better
way.
