Hmm, there apparently *is* a pg_class row for relation 'payment', else
you'd not get this far, and I'll bet it's got OID 672178 --- try "select
oid from pg_class where relname = 'payment'" to see. If so, it seems
likely that this is just an index corruption and you can get out of it
by REINDEXing pg_class_oid_index. Depending on what PG version you are
using, that may require special setup --- read the REINDEX reference
page *for your version* before proceeding.
What version is it, anyway, and what were you doing before you got this
error the first time? This isn't exactly an everyday type of problem.
