I tested last patch and I am thinking so this patch has sense for
custom format too
[postgres@localhost ~]$ /usr/local/pgsql/bin/pg_dump --clean -t a
-Fc postgres > dump
[postgres@localhost ~]$ psql -c "drop table a"
DROP TABLE
[postgres@localhost ~]$ pg_restore --clean -d postgres dump
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 171; 1259 16462 TABLE
a postgres
pg_restore: [archiver (db)] could not execute query: ERROR: table "a"
does not exist
Command was: DROP TABLE public.a;
WARNING: errors ignored on restore: 1
[postgres@localhost ~]$ /usr/local/pgsql/bin/pg_dump --if-exist
--clean -t a -Fc postgres > dump
[postgres@localhost ~]$ psql -c "drop table a"
DROP TABLE
[postgres@localhost ~]$ pg_restore --clean -d postgres dump
So limit for plain format is not too strict
