What the OP was looking for a field in the above that was catalogname or
datname per:
https://www.postgresql.org/docs/current/catalog-pg-database.html
Table "pg_catalog.pg_database"
Column | Type | Collation | Nullable | Default
---------------+-----------+-----------+----------+---------
oid | oid | | not null |
datname | name | | not null |
...
In other words to filter the pg_index results by database/catalog name.
Since pg_index is scoped to the database you are in when you do the
query that is not going to happen.
