OK. I have upgraded mingw and tried to compile. regression tests
passed. So I tested pg_restore on Windows and Linux.
$ createdb test $ pgbench -i -s 1000 test $ pg_dump -Fc test > out $ createdb restore $ pg_restore -d restore out $
psql-c 'select max(aid) from accounts' restore max ----------- 100000000 (1 row)
pg_restore was normally completed. Thank you for your great work. I wish
that the patch will be committed.
