Looks like the same type of error alright. Though I'm building from a
recent git master checkout, and I see the hack was put in place a few
months ago in installation.sgml to convert a troublesome table into a
list. Also, I get the same error on both the -A4 and -US pdf builds.

How did you figure out that the problem was coming from that spot in
installation.sgml? I'd be interested to see whether another hack would
work in lieu of an actual fix in pdftex.

Yeah, I didn't think that was related to the problems I saw, but I
thought it was worth trying to tweak texmf.cnf anyway.

What versions of pdftex are folks who can build these PDFs using? And
is anyone able to build either postgres-A4.pdf or postgres-US.pdf on
Ubuntu or Debian-ish distros using the standard packages? pdftex
--version says for me:

pdfTeX 3.1415926-1.40.10-2.2 (TeX Live 2009/Debian)
kpathsea version 5.0.0
...
Compiled with libpng 1.2.44; using libpng 1.2.44
Compiled with zlib 1.2.3.4; using zlib 1.2.3.4
Compiled with poppler version 0.14.2
