I think this is not correct. since the following three will fail.
$BIN6/pg_dumpall --format=custom --exclude-database=*template* --schema-only
$BIN6/pg_dumpall --format=directory --exclude-database=*template* --schema-only
$BIN6/pg_dumpall --format=tar --exclude-database=*template* --schema-only
that means, pg_dumpall, when format is {custom|directory|tar} --file
option cannot be omitted.
you introduced a format p(plain) for pg_restore? since
$BIN6/pg_restore --dbname=src6 --format=p
will not error out.
but doc/src/sgml/ref/pg_restore.sgml didn't mention this format.
+ if (archDumpFormat == archDirectory)
+ appendPQExpBufferStr(&cmd, " -F d ");
+ else if (archDumpFormat == archCustom)
+ appendPQExpBufferStr(&cmd, " -F c ");
+ else if (archDumpFormat == archTar)
+ appendPQExpBufferStr(&cmd, " -F t ");
can we use long format, i think that would improve the readability.
like changing from
appendPQExpBufferStr(&cmd, " -F d ");
to
appendPQExpBufferStr(&cmd, " --format=directory");

I have tested {pg_dump && pg_restore --list}. pg_restore --list works
fine with format {directory|custom|tar}
but it seems there may be some problems with {pg_dumpall && pg_restore
--list} where format is not plain.
with your v08 patch, in my local environment.
$BIN6/pg_dumpall --format=custom --exclude-database=*template*
--schema-only --file=dumpall_src6.custom
$BIN6/pg_restore --dbname=src6 --verbose --schema-only --list
$SRC6/dumpall_src6.custom
error:
pg_restore: error: option -C/--create should be specified when using
dump of pg_dumpall
$BIN6/pg_restore --dbname=src6 --create --verbose --schema-only --list
$SRC6/dumpall_src6.custom
following is some of the output:
pg_restore: found dbname as : "`s3or" and db_oid:1 in map.dat file
while restoring
pg_restore: found dbname as : "`s3or" and db_oid:5 in map.dat file
