org.postgresql.util.PSQLException: FATAL: n'a pas pu ouvrir le fichier « global/1260 » : Invalid argument (pgjdbc: autodetected server-encoding to be ISO-8859-1, if the message is not readable, please check database logs and/or host, port, dbname, user, password, pg_hba.conf) at org.postgresql.core.v3.ConnectionFactoryImpl.doAuthentication(ConnectionFactoryImpl.java:613) ~[postgresql-42.2.18.jar:42.2.18] at org.postgresql.core.v3.ConnectionFactoryImpl.tryConnect(ConnectionFactoryImpl.java:161) ~[postgresql-42.2.18.jar:42.2.18] at

I try to connect with psql and the same error exist :

psql: erreur : FATAL: n'a pas pu ouvrir le fichier « global/1260 » : Invalid argument

The application has been running in production for 3 months and the error suddenly occurs today.

Answer 1

global/1260 is the pg_authid table, the table of database users. You cannot connect to or use the database without that information.

Somebody or something (file system check?) must have removed PostgreSQL data files. At any rate, you are suffering data corruption, and you need to restore from backup.
