      currently have any better strategy for this query than re-running the
      sub-select over and over; it seems unlikely that doing so 10000 times
      is a more useful test than doing it a few dozen times.

      Call pgstat_drop_database during DROP DATABASE, so that any stats file · f4427117
      Tom Lane authored
      entries for the victim database go away sooner rather than later.  We already
      did the equivalent thing at the per-relation level, not sure why it's not
      been done for whole databases.  With this change, pgstat_vacuum_tabstat
      should usually not find anything to do; though we still need it as a backstop
      in case DROPDB or TABPURGE messages get lost under load.

      < * Merge xmin/xmax/cmin/cmax back into three header fields
      <
      <   Before subtransactions, there used to be only three fields needed to
      <   store these four values. This was possible because only the current
      <   transaction looks at the cmin/cmax values. If the current transaction
      <   created and expired the row the fields stored where xmin (same as
      <   xmax), cmin, cmax, and if the transaction was expiring a row from a
      <   another transaction, the fields stored were xmin (cmin was not
      <   needed), xmax, and cmax. Such a system worked because a transaction
      <   could only see rows from another completed transaction. However,
      <   subtransactions can see rows from outer transactions, and once the
      <   subtransaction completes, the outer transaction continues, requiring
      <   the storage of all four fields. With subtransactions, an outer
      <   transaction can create a row, a subtransaction expire it, and when the
      <   subtransaction completes, the outer transaction still has to have
      <   proper visibility of the row's cmin, for example, for cursors.
      <
      <   One possible solution is to create a phantom cid which represents a
      <   cmin/cmax pair and is stored in local memory.  Another idea is to
      <   store both cmin and cmax only in local memory.

      Combine cmin and cmax fields of HeapTupleHeaders into a single field, by · c3983003
      Tom Lane authored
      keeping private state in each backend that has inserted and deleted the same
      tuple during its current top-level transaction.  This is sufficient since
      there is no need to be able to determine the cmin/cmax from any other
      transaction.  This gets us back down to 23-byte headers, removing a penalty
      paid in 8.0 to support subtransactions.  Patch by Heikki Linnakangas, with
      minor revisions by moi, following a design hashed out awhile back on the
      pghackers list.
