Hi,
I like the idea behind this patch. I wrote a new version with a
couple of changes:
1. Instead of using StringInfoData, just use a small buffer along
with snprintf(). This is similar to what the WAL receiver
process does.
2. If the process is the checkpointer, reset the display to "idle"
once the checkpoint or restartpoint is finished. It's easy
enough to discover the backend type, and I think adding a bit
more clarity to the checkpointer display is a nice touch.
3. Instead of "running," use "creating." IMO that's a bit more
accurate.
I considered also checking that update_process_title was enabled, but
I figured that these ps display updates should happen sparsely enough
that it wouldn't make much of an impact.
What do you think?
Nathan
