Well, like it says at the top of the file, arch-dev.sgml was originally
an extract from Stefan Simkovics' thesis, which one can infer was
prepared in some flavor of TeX.  I doubt that we ever did import the
figures from that, since they didn't match up very well with the
capabilities of our not-TeX docs toolchain.  (A quick look in the
git history seems to confirm this --- Tom Lockhart seems to have
imported the thesis text here:
http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=ba8808b2a668f8f3d1682593915023428f963230
and there's no sign of figures there or in any nearby commit.)

If you're looking for pretty pictures I'd suggest you check out
Bruce's internals talks.  I think this is the current version:
