A system without oideq would be so dead in the water it's not funny ---
consider that all the major catalogs are indexed by oid. It sounds to
me that one particular index's "strategy map" (ie, its in-memory copy
of the relevant indexable-operator info) got trashed. It's hard to
guess why though. Could have been a hardware problem (RAM dropped a
bit) or a software problem (wild store that happened to trash this data
structure rather than anything else).
