问题


I am getting an error after moving the project to production. The error is as follows while running with production server

pg_connect(): Unable to connect to PostgreSQL server: SCRAM authentication requires libpq version 10 or above.

Here is my postgreSQL version:

Development Version :

PostgreSQL 11.5 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36), 64-bit

Production Version :

PostgreSQL 11.5 (EnterpriseDB Advanced Server 11.5.12) on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36), 64-bit

Your application uses an API that is linked with the PostgreSQL client C library libpq.

The version of that library must be 9.6 or older, and SCRAM authentication was introduced in v10.

Upgrade libpq on the application end and try again.

If you don't need scram-sha-256 authentication, you can revert to md5:

  • set password_encryption = md5 in postgresql.conf
  • change the authentication method to md5 in pg_hba_conf
  • reload PostgreSQL
  • change the password of the user to get an MD5 encrypted password

Encountered the same issue and applied @Laurenz Albe's fix but I would get an authentication error on my user for the database, because of encryption strategy change.

So instead of replacing scram-sha-256 with md5, replace it with trust in pg_hba.conf

For windows, postgresql Version 13 seems to show this error. The easy way out is to install postgresql version 12.5 is instead. https://www.enterprisedb.com/downloads/postgres-postgresql-downloads
