Tom Lane fa5e44017a Adjust the API for aggregate function calls so that a C-coded function
can tell whether it is being used as an aggregate or not.  This allows
such a function to avoid re-pallocing a pass-by-reference transition
value; normally it would be unsafe for a function to scribble on an input,
but in the aggregate case it's safe to reuse the old transition value.
Make int8inc() do this.  This gets a useful improvement in the speed of
COUNT(*), at least on narrow tables (it seems to be swamped by I/O when
the table rows are wide).  Per a discussion in early December with
Neil Conway.  I also fixed int_aggregate.c to check this, thereby
turning it into something approaching a supportable technique instead
of being a crude hack.

Tom Lane 595ed2a855 Make the behavior of HAVING without GROUP BY conform to the SQL spec.
Formerly, if such a clause contained no aggregate functions we mistakenly
treated it as equivalent to WHERE.  Per spec it must cause the query to
be treated as a grouped query of a single group, the same as appearance
of aggregate functions would do.  Also, the HAVING filter must execute
after aggregate function computation even if it itself contains no
aggregate functions.

Tom Lane 1fcfa038ce Add a note that regression test row ordering differences can be caused

Tom Lane 5d5087363d Replace the BufMgrLock with separate locks on the lookup hashtable and
the freelist, plus per-buffer spinlocks that protect access to individual
shared buffer headers.  This requires abandoning a global freelist (since
the freelist is a global contention point), which shoots down ARC and 2Q
as well as plain LRU management.  Adopt a clock sweep algorithm instead.
Preliminary results show substantial improvement in multi-backend situations.

2005-02-21 02:13:26 +00:00
Tom Lane 60b2444cc3 Add code to prevent transaction ID wraparound by enforcing a safe limit
in GetNewTransactionId().  Since the limit value has to be computed
before we run any real transactions, this requires adding code to database
startup to scan pg_database and determine the oldest datfrozenxid.
This can conveniently be combined with the first stage of an attack on
the problem that the 'flat file' copies of pg_shadow and pg_group are
not properly updated during WAL recovery.  The code I've added to
startup resides in a new file src/backend/utils/init/flatfiles.c, and
it is responsible for rewriting the flat files as well as initializing
the XID wraparound limit value.  This will eventually allow us to get
rid of GetRawDatabaseInfo too, but we'll need an initdb so we can add
a trigger to pg_database.

Tom Lane f07b9689c9 Generalize TRUNCATE to support truncating multiple tables in one
command.  This is useful because we can allow truncation of tables
referenced by foreign keys, so long as the referencing table is
truncated in the same command.

Tom Lane aba691b728 Close all cursors created during a failed subtransaction. This is needed
to avoid problems when a cursor depends on objects created or changed in
the same subtransaction.  We'd like to do better someday, but this seems
the only workable answer for 8.0.1.

Bruce Momjian b60a8512a0 Update count(*) discussion ideas:
<   BY col {DESC} LIMIT 1. Completing this item involves making this
>   BY col {DESC} LIMIT 1. Completing this item involves doing this
<   invalidated if anyone modifies the table.
<
>   invalidated if anyone modifies the table.  Another idea is to
>   get a count directly from a unique index, but for this to be
>   faster than a sequential scan it must avoid access to the heap
>   to obtain tuple visibility information.
>
> * Allow data to be pulled directly from indexes
>
>   Currently indexes do not have enough tuple tuple visibility
>   information to allow data to be pulled from the index without
>   also accessing the heap.  One way to allow this is to set a bit
>   to index tuples to indicate if a tuple is currently visible to
>   all transactions when the first valid heap lookup happens.  This
>   bit would have to be cleared when a heap tuple is expired.
