question regarding pg_database.h and DatabaseRelationId
Hello all,
Could someone explain the numbering logic in naming the relations? Why
#define DatabaseRelationId 1262.
I guess not being involved from the beginning has its disadvantages. but
it is very exiting and fun trying to learn the internals by gdb and
asking lots of questions :)
Regards,
Gevik.

There is none. The numbers are presumably assigned in some
lowest-available manner, but over the years it has become pretty
random.

In the src/include/catalog directory there are two scripts, unused_oids
and duplicate_oids. When you need a new oid you run the unused_oids and
pick one somewhere near the rows with similar meaning. The numbers are
so all over the place that you may as well consider them random...
