Very nice. You did a nice trick of reading the log filenames into a timestamp field:
count = sscanf(de->d_name, "%04d-%02d-%02d_%02d%02d%02d_%05d.log", &yea$
You only process files that match that pattern for pg_logfiles_ls() (perhaps this should be pg_logdir_ls for consistency).
Yup.
And you can then
process the timestamp field in queries. Good idea. What happens if a filename matches the above pattern but isn't a valid timestamp? Does the function fail?
Right now, BuildTupleFromCString will fail for invalid timestamps.
I'm going to change that to pgsql's internal function (strptime seems a bad idea though).
My only question is whether we need to allow a custom prefix for the log filenames so they can be distinguished from other file names in a user-supplied log directory, like /var/log, or would they always go into a separate directory under there. I think a prefix would be nice.
How should the prefix be named? pgsql_ ?
Of course this needs docs but I assume you are waiting to see it applied first.
Not necessarily, but I'd like names etc. fixed before.
