Question

I moved my PostgresQL database from one hard drive to another using

pg_dump -U postgres db_name > db_name.dump

and then

psq         


        

Answer 1

Are you moving to the same version of PostgreSQL? There might be issues if you make a dump with pg_dump 8.3 and try to restore it in Postgresql 8.4. Anyway, assuming that it is the same version try the following:

Dump all global objects, such as users and groups (don't know if they were missing in your dump):

pg_dumpall -g -U postgres > globals.sql

Dump schema of database:

pg_dump -Fp -s -v -f db-schema.sql -U postgres dbname

Dump contents of database:

pg_dump -Fc -v -f full.dump -U postgres dbname

Now restore.

psql -f globals.sql
psql -f db-schema.sql dbname
pg_restore -a -d dbname -Fc full.dump

That is my $0.02. Hope it helps.

Answer 2

I was able to solve it by changing the database privileges to public CONNECT and the schema privileges for public and postgres = USAGE and CREATE.

My backup scripts apparently didn't preserve the privileges, at least not when moving from 8.3 to 8.4.

Answer 3

I encountered this problem. Then I realized that I forgot to install postgis extension.

Don't forget to install the extensions you use.
