Now that we have numeric file names, I would like to have a command I
can run from psql that will dump a mapping of numeric file name to table
name, i.e.,
121233 pg_proc143423 pg_index
With that feature, I can write scripts pgfile2name and pgname2file that
map file names to table names. People can run standard Unix commands
and have meaningful display output:
ls -l | pgfile2name
changes:
-rwx------ 4 postgres postgres 512 Oct 27 10:52 198323
to:
-rwx------ 4 postgres postgres 512 Oct 27 10:52 pg_class
The only missing piece would be to identify files on a backup tape. Not
sure how to handle that unless a map file already exists on the tape.
