is about an 18-hour span, covering 12.5M transactions, on
version 8.3.18:

(13 times) Various OIDs that do exist cannot be found:
ERROR:  XX000: could not open relation with OID 1554847444
LOCATION:  relation_open, heapam.c:879

(21 times) Relations that do exist cannot be found:
ERROR:  42P01: relation "foobar" does not exist
LOCATION:  RangeVarGetRelid, namespace.c:273

(1 time) Qualified relation that exists cannot be found:
ERROR:  42P01: relation "public.foobar" does not exist
LOCATION:  RangeVarGetRelid, namespace.c:268

(5 times) Failure to read a block:
XX001: could not read block 3 of relation 1663/1554846571/4184054438: read only 0 of 8192 bytes
