Fujii Masao b70d5672d0 pg_buffercache: restore rowtype verification in pg_buffercache_pages() ... Commit 257c8231bf changed pg_buffercache_pages() to materialize its output directly into a tuplestore. As a result, the function ended up trusting a caller-supplied RECORD descriptors. That could lead to crashes if the supplied row definition did not match the actual returned values, for example by passing bool Datums to tuplestore_putvalues() with an incompatible descriptor. Fix this by constructing the correct tuple descriptor for pg_buffercache_pages() and assigning it to rsinfo->setDesc after InitMaterializedSRF(). This restores the executor's tupledesc_match() verification, so incompatible caller-supplied row definitions are rejected with an error, as before commit 257c8231bf.
