Agreed, doing it with a TAP test removes the complication.
Some other small comments:
+ Assert(PQserverVersion(conn) >= 140000);
Are these assertions really buying us much when we already check the server
version in reindex_one_database()?
+ printf(_(" --tablespace=TABLESPACE reindex on specified tablespace\n"));
While not introduced by this patch, I realized that we have a mix of
conventions for how to indent long options which don't have a short option.
Under "Connection options" all options are left-justified but under "Options"
all long-options are aligned with space indentation for missing shorts. Some
tools do it like this, where others like createuser left justifies under
Options as well. Maybe not the most pressing issue, but consistency is always
good in user interfaces so maybe it's worth addressing (in a separate patch)?
