You mean the text input function did stomp over shared memory of the
buffer cache? That would be the first time I hear of this.
Could you please do
select oid as datoid from pg_database where datname = '<dbname>';
select A.relfilenode from pg_class A, pg_class B, pg_class C where C.relname = '<tablename>' and B.oid =
C.reltoastrelid and A.oid = B.reltoastidxid;
With that information, give us an
ls -l $PGDATA/base/<datoid>/<relfilenode>
This file is the toast tables index.

Is there more information about why it wasn't reindexed in the
postmaster log?

As you might guess from the second select above ...
