This one better describes the problem.

heap.c needs to be updated to include 'Hard coded badness' for that
table.

This directory contains .c files that manipulate the system catalogs
as well as .h files that define the structure of the system catalogs.

If you need to find a valid OID for a set of tuples that refer to each
other, use the unused_oids script. It generates inclusive ranges of
*unused* OIDs (i.e., the line "45-900" means OIDs 45 through 900 have
not been allocated yet). However, you should not rely 100% on this
script, since it only looks at the .h files in the catalog/ directory.
Do a pg_grepsrc (recursive grep) of the source tree to insure that
there aren't any hidden crocks (i.e., explicit use of a numeric OID)
anywhere in the code. (tgl 1/2002: that advice is obsolete; there are
no hardcoded uses of OIDs in the C files anymore. All OIDs that are known
directly to C code should be referenced via #defines in the catalog .h files.
So unused_oids is sufficient for assigning new OIDs.)

script simply 'discovers' those which are free.
- BOOTSTRAP tables must be at the start of the Makefile POSTGRES_BKI_SRCS
variable, as these will not be created through standard function means, but
will be written directly to disk. Thats how pg_class is created without
depending on functions which depend on the existance of pg_class. The
list of files this currently includes is:
pg_proc.h pg_type.h pg_attribute.h pg_class.h
Don't forget to add the entry to heap.c to function heap_create() which
sets the OID of the relation when it's a bootstrapped system table. It's
near the top of the function with the comment beginning in 'Real ugly stuff'
