I have two installation of postgresql-server-9.2.4 on Gentoo. I try to just copy database from one to another. According to the documentation http://www.postgresql.org/docs/9.2/static/backup-dump.html I created dump file: psql -U <role> <database> > dumpfile.sql copied it to another machine, manually created the same role, database and schema (owned by user) as in the first machine and tried to restore: psql -f dumpfile.sql -U <role> <database> It produces a lot of errors starting from the first command in dumpfile: DROP TABLE "archive" CASCADE\g that produces error: ERROR: table "archive" does not exist The second comand is creation of this table: CREATE TABLE "archive" ( "ar_namespace" int NOT NULL DEFAULT '0', "ar_title" bytea NOT NULL DEFAULT '', "ar_text" bytea NOT NULL, "ar_comment" bytea NOT NULL, "ar_user" int CHECK ("ar_user" >= 0) NOT NULL DEFAULT '0', "ar_user_text" bytea NOT NULL, "ar_timestamp" bytea NOT NULL DEFAULT '\0\0\0\0\0\0\0\0\0\0\0\0\0\0', "ar_minor_edit" smallint NOT NULL DEFAULT '0', "ar_flags" bytea NOT NULL, "ar_rev_id" int CHECK ("ar_rev_id" >= 0) DEFAULT NULL, "ar_text_id" int CHECK ("ar_text_id" >= 0) DEFAULT NULL, "ar_deleted" smallint CHECK ("ar_deleted" >= 0) NOT NULL DEFAULT '0', "ar_len" int CHECK ("ar_len" >= 0) DEFAULT NULL, "ar_page_id" int CHECK ("ar_page_id" >= 0) DEFAULT NULL, "ar_parent_id" int CHECK ("ar_parent_id" >= 0) DEFAULT NULL, "ar_sha1" bytea NOT NULL DEFAULT '', "ar_content_format" bytea DEFAULT NULL, "ar_content_model" bytea DEFAULT NULL ) ; it produces error: ERROR: invalid input syntax for type bytea and so on... a lot of error relation/table does not exist. In the initial database field "ar_title" in table "archive" has type "text", not "bytea". At the end I have only 45 tables of 51 in my new database. In the man page of pg_dump I can see option -c, --clean that as far as I understand should activate existance of DROP TABLE commands in dump. I didn't add this option but have such commands.
