When encountering the error 42939: Reserved Name in Postgres, it indicates you're trying to use a name for a database object (like a table, column, etc.) that is reserved by PostgreSQL for its internal use. Here's what you can do immediately:
- Identify the Object Name: Look at the operation you were trying to perform when the error occurred. Identify the name you were trying to assign to your object.
- Check PostgreSQL Documentation: Briefly check PostgreSQL documentation to confirm if the name you're using is indeed reserved. The list of reserved keywords can be found here: PostgreSQL Reserved Keywords.
- Rename the Object: Choose a different name for your object that is not on the reserved list. Make sure the new name does not conflict with PostgreSQL's reserved keywords.
- Execute the Renamed Operation: After renaming, execute your operation again with the new name. For example, if you were trying to create a table, your command might look something like this:
CREATE TABLE new_name (
-- your table definition goes here
);
- Monitor Logs: If possible, check the PostgreSQL log for any additional error messages or warnings that can provide more context about the issue. The log location depends on your PostgreSQL installation and configuration, but you can find it with:
SHOW log_directory;
Remember, without a database administrator, proceed with caution, especially if making changes in a production environment.
