Please find attached a quick patch to prevent this particularly bad error
message for running "postgres", when making the common mistake of
forgetting to put the "--single" option first because you added an earlier
arg (esp. datadir)
Current behavior:
$ ~/pg/bin/postgres -D ~/pg/data --single
2024-06-05 18:30:40.296 GMT [22934] FATAL: --single requires a value
Improved behavior:
$ ~/pg/bin/postgres -D ~/pg/data --single
--single must be first argument.
I applied it for all the "first arg only" flags (boot, check,
describe-config, and fork), as they suffer the same fate.
Cheers,
Greg
