PostgresDB 42622: Name Too Long

What is PostgresDB 42622: Name Too Long

Identify the specific operation causing the error (e.g., table creation, column addition). Use application logs or PostgreSQL logs to find the exact query.Check the length of the name causing the error. PostgreSQL has a limit of 63 bytes for identifiers (names of tables, columns, etc.). Use the strlen() function in your application or scripting language to measure the length of the name in bytes, considering character encoding.SELECT LENGTH('your_identifier_name_here');If the name exceeds 63 bytes, shorten the name to comply with the PostgreSQL limit and retry the operation.If altering the identifier directly isn't feasible or doesn't resolve the issue, consider creating an alias or a temporary variable in your application logic to hold the long identifier, ensuring the alias used in the PostgreSQL query does not exceed the 63-byte limit.If needed, you can also query the current setting for the maximum identifier length (though changing this setting is not recommended as it requires recompiling PostgreSQL):SHOW max_identifier_length;After making adjustments, rerun your query or application function to verify the resolution of the error.
