There will be dirty heap & index buffers in the pool after insertion ...

They are still marked as dirty...

heap_destroy_with_catalog () calls ReleaseRelationBuffers:

 *      this function unmarks all the dirty pages of a relation
 *      in the buffer pool so that at the end of transaction
 *      these pages will not be flushed.

before unlinking relation, BUT index_destroy() unlinks index
and DOESN'T call this func ...

COMMIT (of drop table) tries to flush all dirty buffers
from pool but there is no index file any more ...

smgrblindwrt () fails.

...transaction state is IN_COMMIT...

Seems that ReleaseRelationBuffers() should be called by
index_destroy() ... Note that heap_destroy() also calls

    /* ok - flush the relation from the relcache */
    RelationForgetRelation(rid);

at the end...
