Now that I proposed a new syscache upthread its easily possible to provide
pg_relation_by_filenode which I wished for multiple times in the past when
looking at filesystem activity and wondering which table does what. You can
sortof get the same result via
SELECT oid FROM (
SELECT oid, pg_relation_filenode(oid::regclass) filenode
FROM pg_class WHERE relkind != 'v'
) map
WHERE map.filenode = ...;
but thats neither efficient nor obvious.
So, two patches to do this:
Did others need this in the past? I can live with the 2nd patch living in a
private extension somewhere. The first one would also be useful for some
error/debug messages during decoding...
Greetings,
Andres
