"txn" in pg_stat_activity
I have just noticed that a column "txn_start" has appeared in
pg_stat_activity since 8.2. It's a good idea, but who chose the name?
We do not use that abbreviation for "transaction" anywhere else in
Postgres, certainly not in any user-exposed places.
I'm inclined to rename it to "xact_start", which is an abbreviation
that we *do* use in the code, and in some user-visible places, eg,
pg_stat_database has "xact_commit" and "xact_rollback" columns.
Other suggestions? If we don't change it before 8.3 beta starts,
we'll be stuck with it ...

I personally find "xact" to be a less intuitive abbreviation of
"transaction" than "txn", but for the sake of consistency, I agree it is
probably better to use "xact_start".

Barring other objections, I'll go make this happen.
