This looks correct to me. Thanks for the fix.
Your use of strtoul compares favorably to that in pg_resetwal in that you are checking errno and it is not. The
consequenceis:
bin % ./pg_resetwal/pg_resetwal -e 1111111111111111111111111111111111111111111111111111
pg_resetwal: error: transaction ID epoch (-e) must not be -1
bin % ./pg_resetwal/pg_resetwal -e junkstring
pg_resetwal: error: invalid argument for option -e
Try "pg_resetwal --help" for more information.
Unless people are relying on this behavior, I would think pg_resetwal should complain of an invalid argument for both
ofthose, rather than complaining about -1. That's not to do with this patch, but if we're tightening up the use of
strtolin frontend tools, maybe we can use the identical logic in both places.
