We are using PostgreSQL 12.3 and it is running under Windows environment. In my server multiple databases are available. When we try to Back up one of the database, it gives the following error message, we can able to connect and read & write to the database. But unable to back up the database , We faced this issue on one database only, remaining databases are working good and able to backup. Suggest me, How to resolve this issue. pg_dump: last built-in OID is 16383 pg_dump: reading extensions pg_dump: identifying extension members pg_dump: reading schemas pg_dump: reading user-defined tables pg_dump: reading user-defined functions pg_dump: reading user-defined types pg_dump: error: schema with OID 1020797 does not exist Thanks, Karthick Ramu |
