* update_attstats() -- update attribute statistics for one relation

* Statistics are stored in several places: the pg_class row for the
* relation has stats about the whole relation, and there is a
* pg_statistic row for each (non-system) attribute that has ever
* been analyzed. The pg_class values are updated by VACUUM, not here.
*
* pg_statistic rows are just added or updated normally. This means
* that pg_statistic will probably contain some deleted rows at the
* completion of a vacuum cycle, unless it happens to get vacuumed last.
*
* To keep things simple, we punt for pg_statistic, and don't try
* to compute or store rows for pg_statistic itself in pg_statistic.
* This could possibly be made to work, but it's not worth the trouble.
* Note analyze_rel() has seen to it that we won't come here when
* vacuuming pg_statistic itself.
*
* Note: if two backends concurrently try to analyze the same relation,
* the second one is likely to fail here with a "tuple concurrently
* updated" error. This is slightly annoying, but no real harm is done.
* We could prevent the problem by using a stronger lock on the
* relation for ANALYZE (ie, ShareUpdateExclusiveLock instead
* of AccessShareLock); but that cure seems worse than the disease,
* especially now that ANALYZE doesn't start a new transaction
* for each relation. The lock could be held for a long time...

* update_attstats() -- update attribute statistics for one relation
*
* Statistics are stored in several places: the pg_class row for the
* relation has stats about the whole relation, and there is a
* pg_statistic row for each (non-system) attribute that has ever
* been analyzed. The pg_class values are updated by VACUUM, not here.
*
* pg_statistic rows are just added or updated normally. This means
* that pg_statistic will probably contain some deleted rows at the
* completion of a vacuum cycle, unless it happens to get vacuumed last.
*
* To keep things simple, we punt for pg_statistic, and don't try
* to compute or store rows for pg_statistic itself in pg_statistic.
* This could possibly be made to work, but it's not worth the trouble.
* Note analyze_rel() has seen to it that we won't come here when
* vacuuming pg_statistic itself.
*
* Note: if two backends concurrently try to analyze the same relation,
* the second one is likely to fail here with a "tuple concurrently
* updated" error. This is slightly annoying, but no real harm is done.
* We could prevent the problem by using a stronger lock on the
* relation for ANALYZE (ie, ShareUpdateExclusiveLock instead
* of AccessShareLock); but that cure seems worse than the disease,
* especially now that ANALYZE doesn't start a new transaction
* for each relation. The lock could be held for a long time...

/*----------
* ANALYZE builds one of these structs for each attribute (column) that is
* to be analyzed. The struct and subsidiary data are in anl_context,
* so they live until the end of the ANALYZE operation.
*
* The type-specific typanalyze function is passed a pointer to this struct
* and must return TRUE to continue analysis, FALSE to skip analysis of this
* column. In the TRUE case it must set the compute_stats and minrows fields,
* and can optionally set extra_data to pass additional info to compute_stats.
*
* The compute_stats routine will be called after sample rows have been
* gathered. Aside from this struct, it is passed:
* attnum: attribute number within the supplied tuples
* tupDesc: tuple descriptor for the supplied tuples
* totalrows: estimated total number of rows in relation
* rows: an array of the sample tuples
* numrows: the number of sample tuples
* Note that the passed attnum and tupDesc could possibly be different from
* what one would expect by looking at the pg_attribute row. It is important
* to use these values for extracting attribute values from the given rows
* (and not for any other purpose).
*
* compute_stats should set stats_valid TRUE if it is able to compute
* any useful statistics. If it does, the remainder of the struct holds
* the information to be stored in a pg_statistic row for the column. Be
* careful to allocate any pointed-to data in anl_context, which will NOT
* be CurrentMemoryContext when compute_stats is called.
