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.
