Hi
In cost functions such as cost_seqscan, a RelOptinfo indicate a base
relation.
But there is no relfilenode in the RelOptinfo, So how could i find
relfilenode or reloid of the relation?
Thanks,

Hi
When PG crashes or the computer turned down unexpectedly, next time
postmaster
starts up, it does the crash recovery, actually redo xlog records, vacuum,
etc.
What module is responsible for crash recovery?

this is equivalent to pg_class.relfilenode and in some
situation relation oid (pg_class.oid) and relation file node are not the
same.
So i cant use above function!
Any idea?

Why do you think you need to do that? Such a lookup is inherently the
wrong thing, because relations
test_myvarchar_i_plain on test_myvarchar
(cost=0.41..6099.0
8 rows=31175 width=197)
Index Cond: ('zagftha'::text = (plain)::text)
Why planner does not choose the lowest cost path?
Is there any problem with my new type? How can I fix it?
Any help would be appreciated.

I want to find what table stored in each file.
BTW, I read this
http://www.postgresql.org/docs/9.2/interactive/storage-file-layout.html
I have 156 files with numerical names, vm and fsm
Yes, I have some files which is not in pg_class.relfilenode of any table or

I want to know which table or index stored in such files.
From that page:
Each table and index is stored in a separate file. For ordinary
relations, these files are named after the table or index's filenode
which exists in newfile.pg and does not
in filenode.pg
