What is
PostgresDB 22021: Character Not in Repertoire
?
When encountering the error 22021: Character Not in Repertoire from a Postgres database, the user should directly investigate the nature of the data causing this error. This error occurs when an attempt is made to store or use characters in the database that are not supported by the database encoding or the specific column's encoding.
- Identify the Query Causing the Error: The first step is to pinpoint the query that triggered this error. If you already know which operation caused it, you proceed to step 2. If not, review the application logs or the Postgres log file to identify the problematic query.
- Check Database and Client Encoding: Run the following commands in the psql terminal to check the database and client encoding settings.
SHOW server_encoding;
SHOW client_encoding;- This will help you understand if there's a mismatch between the encoding expected by the database and the encoding of the input data.
- Examine the Data: Once you've identified the offending query, closely examine the data it's trying to insert or update. Look for any unusual characters, especially those that might not be supported by the current encoding of your database or table.
- Adjust the Query: If you find characters that are likely causing the issue, you may need to either:
- Remove or replace those characters in the input data.
- Use the
convert_toandconvert_fromfunctions to properly encode the data before insertion.
- Example:
INSERT INTO your_table (your_column) VALUES (convert_to('Your text here', 'TARGET_ENCODING'));- Replace
'Your text here'with your actual data and'TARGET_ENCODING'with the encoding needed (like 'UTF8'). - Consider Setting Client Encoding: If your data source uses a different encoding, you can set the client encoding to match your source data encoding before running the query.
SET client_encoding TO 'desired_encoding';- Replace
'desired_encoding'with the correct encoding that matches your data source. - Test with a Small Subset: Before applying the changes to your production database, test the adjusted query or encoding settings with a small subset of data to ensure it resolves the issue without causing data corruption.
These steps are immediate actions targeted at identifying and potentially resolving the 'Character Not in Repertoire' error directly.
