Hints

Creating a new index on an existing table

ID: E6

A new index was created on an existing table without the CONCURRENTLY keyword. This blocks all writes to the table while the index is being created. A safer way is: Run CREATE INDEX CONCURRENTLY instead of CREATE INDEX.

A new index was created on the table public.authors. The index public.authors_name_idx was created non-concurrently, which blocks all writes to the table. Use CREATE INDEX CONCURRENTLY to avoid blocking writes.
