You seem to have a rather badly broken copy of Postgres :-( Does it
pass the regression tests? (I'd bet not.)
PG 7.4 is known to run on Linux/Alpha, and since the report in the
"supported platforms" table is from someone at debian.org, I would
imagine that test was specifically on Debian. So it ought to work
for you. Perhaps you got a corrupted download, or used a buggy
compiler to build it, or some such.
