The buildfarm release landed 2019-04-04, so I pushed $SUBJECT today, in commit
bd1592e. The buildfarm was unanimous against it, for two reasons. First, the
patch was incompatible with NO_TEMP_INSTALL=1, which the buildfarm uses. In a
normal "make -C src/bin/pg_upgrade check", the act of creating the temporary
installation also creates "tmp_check". With NO_TEMP_INSTALL=1, it's instead
the initdb that creates "tmp_check". I plan to fix that by removing and
creating "tmp_check" early. This fixes another longstanding bug; a rerun of
"vcregress upgradecheck" would fail with 'directory "[...]/tmp_check/data"
exists but is not empty'. It's also more consistent with $(prove_check),
eliminates the possibility that a file in "tmp_check" survives from an earlier
run, and ends NO_TEMP_INSTALL=1 changing the "tmp_check" creation umask.
Second, I broke "vcregress installcheck" by writing "funcname $arg" where
funcname was declared later in the file. Neither the function invocation
style nor the function declaration order were in line with that file's style,
so I'm changing both.
