I exported a postgres db from pgAdmin in a plain format because I wanted to search the whole db text. I then tried to restore the database back but it gives an error saying that the archive file is not valid archive file. How do I restore the db back if it can be restored?



psql -U your_user_name your_db_name < your_dump_file

  • it should, if psql frontend is included in the postgresql package. Try to fire up a terminal, then cd to postgresql bin directory and try to run psql – guido Feb 21 '12 at 11:13
  • I tried it now. It didnt work. There is psql.bat file in the postgres bin directory. I am using postgres 8.3 – yankitwizzy Feb 21 '12 at 11:17
  • what do you mean with 'it didnt work'? if there is psql.bat however, try with that, it should run psql. look here for help archives.postgresql.org/pgsql-admin/2006-12/msg00091.php – guido Feb 21 '12 at 11:22
  • Sorry I meant there is no psql.bat file in the bin directory – yankitwizzy Feb 21 '12 at 11:27

If you are using a newer version of PostgreSQL (9+ or so), you'd use something like:

psql -U <username> -d <database name> -1 \i D:/Database/file.sql

Beware that the command above works on Windows. For Linux you'd of course change the forward slashes and the chmod if necessary.
