Обсуждение: Possible problem with type bigserial in pg_dump/pg_restore

It seems to have a problem when making backup and restore with type bigserial. I perceived when was restoring a database and the sequence created for field bigserial was not correctly restored.

For example, i've created the follow structure:

CREATE TABLE cager.princ
(
  cd_princ bigserial NOT NULL,
  nm_princ character varying(50),
  CONSTRAINT "pk-princ-cd_princ" PRIMARY KEY (cd_princ)
)
WITHOUT OIDS;

Making backup with:
C:\Arquivos de programas\pgAdmin III\1.6\pg_dump.exe -i -h 192.168.7.1 -p 5432 -U postgres -F c -b -v -f "C:\Temp\testepad.backup" testepad

Making restore with:
C:\Arquivos de programas\pgAdmin III\1.6\pg_restore.exe -i -h 192.168.7.1 -p 5432 -U postgres -d test1 -v "C:\Temp\testepad.backup"

The same table now is:

CREATE TABLE cager.princ
(
  cd_princ bigint NOT NULL DEFAULT nextval('princ_cd_princ_seq'::regclass),
  nm_princ character varying(50),
  CONSTRAINT "pk-princ-cd_princ" PRIMARY KEY (cd_princ)
)
WITHOUT OIDS;

Take a look at the field cd_princ. Next value should be 'cager.princ_cd_princ_seq'.

I've tested it with pg_admin version 1.6.2 and 1.4.3.

If need more information, please, contact me.

Don't use a pg_dump/pg_restore that are newer than your server version.
