Hello Peter,
I think pg_dump/t/002_pg_dump.pl might be a good place. Not the easiest
program in the world to work with, admittedly.
Updated patch with test and expanded documentation.
Patch v2 applies cleanly, compiles, make check-world ok with tap enabled.
Doc gen ok.
The addition looks reasonable.
The second error message about conflicting option could more explicit than
a terse "conflicting or redundant options"? The user may expect later
options to superseedes earlier options, for instance.
About the pg_dump code, I'm wondering whether it is worth generating
LOCALE as it breaks backward compatibility (eg dumping a new db to load it
into a older version).
If it is to be generated, I'd do merge the two conditions instead of
nesting.
if (strlen(collate) > 0 && strcmp(collate, ctype) == 0)
// generate LOCALE
