Oh, I see. I'm sorry, I misread your earlier suggestion. Regenerated
patches attached. Is this what you had in mind?
Committed the patch to add INT64_MODIFIER, with minor fixes.
The new rm_identify method needs to be documented. Not sure where;
surprisingly I can't find any documentation on the existing methods
either. Perhaps add comments to the RmgrData struct, explaining all of
the methods. In particular, should give guidelines on what output
belongs in rm_desc and what in rm_identify.
I think the names that rm_identify returns should match those that the
rm_desc functions print. As the patch stands, for example when heap_desc
prints out something like:
hot_update(init): xmax 123; new tid 1/2 xmax 456
The corresponding rm_identify output is:
HOT_UPDATE+INIT
It would be better to spell them the same, so that when you look at the
summary stats and the raw pg_xlogdump output, you can tell which records
contributed to which summary line.
