All we need is an easy explanation of the problem, so here it is.
We need to migrate our existing database server (PG 12) to a new server.
I followed this [https://www.postgresql.org/docs/8.1/app-pg-dumpall.html] article and created the dump as
pg_dumpall > alldb.sql
then copied the file
alldb.sql to the new system and tried to restore using
psql -f alldb.sql postgres
and it failed with the following error messages
psql:allbackup.sql:314: ERROR: option "locale" not recognized LINE 1:
…3103" WITH TEMPLATE = template0 ENCODING = ‘UTF8’ LOCALE = ‘…
^ psql:allbackup.sql:317: ERROR: database "XXXXX" does not exist
psql:allbackup.sql:319: error: \connect: FATAL: database "XXXXX"
does not exist
What could be the issue?
- Ubuntu 20.04
- Postgres version 12
How to solve :
I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.
CREATE DATABASE statement did not accept a
LOCALE parameter until PostgreSQL version 13. It fails in your case because the target server is version 12.
pg_dumpall command put that parameter because its version is newer than 12, so it considers that you’re going to restore into a version newer than 12. You can check the version with
The solution is to use the same version of
pg_dumpall than your target server. On Ubuntu, you might have several versions installed. Check if you have
/usr/lib/postgresql/12/bin/pg_dumpall, and if you do, call it directly with that full path.
If it’s not installed, it can be installed with the
Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
