I downloaded the postgresql .dmp file from the chembl database.
I want to import this into gcp cloudsql.
When I run it with the console and gcloud command, I get the following error:
Importing data into Cloud SQL instance...failed.
ERROR: (gcloud.sql.import.sql) [ERROR_RDBMS] exit status 1
The input is a PostgreSQL custom-format dump.
Use the pg_restore command-line client to restore this dump to a database.
Can I import custom-format dmp files without using the pg_restore command?
https://cloud.google.com/sql/docs/postgres/import-export/importing
There is a description of pg_restore in the document on that site, but I didn't get it right.
In the case of custom-format files, is it necessary to pg_restore after uploading them to the cloud shell?
According to the CloudSQL docs:
Only plain SQL format is supported by the Cloud SQL Admin API. The custom format is allowed if the dump file is intended for use with pg_restore.
If you cannot use pg_restore for some reason, I would spin up a local Postgres instance (i.e., on your laptop) and use pg_restore to restore the database.
After loading into your local database, you can use pg_dump to dump to file in plaintext format, then load into CloudSQL with the console or gcloud command.
