I reproduced this locally, and the problem seems to be that
CloneArchive() is doing a far-less-than-half-baked job of
reconstructing the original connection parameters.
The data that PQconnectdbParams gets is just
(gdb) p keywords
$1 = {0x44ef22 "host", 0x44d52d "port", 0x44e4f0 "user", 0x4532b6 "password",
0x44ef14 "dbname", 0x45325f "fallback_application_name", 0x0}
(gdb) p values
$2 = {0x25459e0 "127.0.0.1", 0x25459a0 "5432", 0x2545180 "postgres", 0x0,
0x2a61d60 "dbname=regression", 0x2538410 "pg_dump", 0x0}
so parallel pg_dump is basically guaranteed to fail in any
case with even slightly unusual connection parameters.
Not sure why we should be trying to do it like that at
all; it'd be better if the original command-line parameters
got passed down in all cases. Looking at that now.
