It seemed the appropriate scope for my first submission, and that feature has
been on my wish list for a while, so I thought I'd grab it.
I've reviewed the patch (though haven't tested it myself) and it looks good.
The only thing I'm not sure of is this:
+ /* Get the timestamp of the current statistics snapshot */
+ Datum
+ pg_stat_snapshot_timestamp(PG_FUNCTION_ARGS)
+ {
+ PG_RETURN_TIMESTAMPTZ(pgstat_fetch_global()->stats_timestamp);
+ }
Is the community OK with referencing stats_timestamp that way?
