Consider had Vadim made this proposal (set the time-travel machine to 
version 7.1.2 or so):
"I'm going to remove WAL from Postgres, so that we can use the table name as the filename for the table on disk."

So, no, rather than being a major pain, I'd classify it as a minor
inconvenience.  If it becomes, in fact, a major pain, one can always
write a two-line psql script that prints a table name, given an oid.

On an unrelated matter, I haven't been following the "limit elimination"
effort as closely as I should have.  Is it now possible to compile Postgres
with 16Kb tuple size, and insert/select 15Kb text fields from the tuples?
