Answer from AI

To view information about the structure and status of an index in a database, system commands or queries are usually used, depending on the specific DBMS.

For example, in PostgreSQL, you can execute the following query:

SELECT * FROM pg_stat_user_indexes WHERE indexrelname = 'index_name';

Or view the index structure through:

REINDEX VERBOSE index_name;

In Go, you can use the database/sql package to execute the corresponding SQL query and process the result.

Example in Go:

rows, err := db.Query("SELECT * FROM pg_stat_user_indexes WHERE indexrelname = $1", indexName)
if err != nil {
    log.Fatal(err)
}
// Process rows

Thus, to view index information, you need to know the specific DBMS and use its tools or SQL queries.
