Message-ID: <E1rFTTr-00Askx-Kq@gemulon.postgresql.org> (raw)
pgstattuple: Fix failure with pgstathashindex() for partitioned indexes
As coded, the function relied on index_open() when opening an index
relation, allowing partitioned indexes to be processed by
pgstathashindex(). This was leading to a "could not open file" error
because partitioned indexes have no physical files, or to a crash with
an assertion failure (like on HEAD).
This issue is fixed by applying the same checks as the other stat
functions for indexes, with a lookup at both RELKIND_INDEX and the index
AM expected.
