I think something else must be going on. The failure in question came 
after the step "install-contrib" succeeded, and the log file for that shows:


make[1]: Entering directory `/opt/postgres/build-farm-18/HEAD/pgsql.build/contrib/amcheck'
/usr/bin/mkdir -p '/opt/postgres/build-farm-18/HEAD/pgsql.build/tmp_install/opt/postgres/build-farm-18/HEAD/inst/lib'

make[1]: Leaving directory `/opt/postgres/build-farm-18/HEAD/pgsql.build/contrib/amcheck'


(wondering if this another of these cases where the "path includes postgres" thing bites us, and we're looking in the wrong place)

Buildfarm member snakefly doesn't like this too much.  Since no other
animals have failed, I guess it must be about local conditions on
that machine, but the report is pretty opaque:

Looking at the test, it presupposes that "amcheck" must be an
available extension.  I do not see anything that guarantees
that that's so, though.  It'd fail if contrib hasn't been
installed.  Is there a reason to use "amcheck" rather than
something more certainly available, like "plpgsql"?</pre>
