instead of the former kluge whereby gram.y emitted already-transformed
expressions. This is needed so that Params appearing in these clauses
actually work correctly. I suppose some might claim that the side effect
of 'SELECT ... LIMIT 2+2' working is a new feature, but I say this is
a bug fix.

It also works to create a non-polymorphic aggregate from polymorphic

lacking. By Joe Conway, with some kibitzing from Tom Lane.

body until runtime. Documentation is still lacking.

node emits only those vars that are actually needed above it in the
plan tree. (There were comments in the code suggesting that this was
done at some point in the dim past, but for a long time we have just
made join nodes emit everything that either input emitted.) Aside from
being marginally more efficient, this fixes the problem noted by Peter
Eisentraut where a join above an IN-implemented-as-join might fail,
because the subplan targetlist constructed in the latter case didn't
meet the expectation of including everything.
Along the way, fix some places that were O(N^2) in the targetlist
length. This is not all the trouble spots for wide queries by any
means, but it's a step forward.

'scalar op ALL (array)', where the operator is applied between the
lefthand scalar and each element of the array. The operator must
yield boolean; the result of the construct is the OR or AND of the
per-element results, respectively.
Original coding by Joe Conway, after an idea of Peter's. Rewritten
by Tom to keep the implementation strictly separate from subqueries.

comparison functions), replacing the highly bogus bitwise array_eq. Create
a btree index opclass for ANYARRAY --- it is now possible to create indexes
on array columns.
Arrange to cache the results of catalog lookups across multiple array
operations, instead of repeating the lookups on every call.
Add string_to_array and array_to_string functions.
Remove singleton_array, array_accum, array_assign, and array_subscript
functions, since these were for proof-of-concept and not intended to become
supported functions.
Minor adjustments to behavior in some corner cases with empty or
zero-dimensional arrays.
Joe Conway (with some editorializing by Tom Lane).

Regression tests for IPv6 operations added.
Documentation updated to document IPv6 bits.
Stop treating IPv4 as an "unsigned int" and IPv6 as an array of
characters. Instead, always use the array of characters so we
can have one function fits all. This makes bitncmp(), addressOK(),
and several other functions "just work" on both address families.
add family() function which returns integer 4 or 6 for IPv4 or
IPv6. (See examples below) Note that to add this new function
you will need to dump/initdb/reload or find the correct magic
to add the function to the postgresql function catalogs.
IPv4 addresses always sort before IPv6.
On disk we use AF_INET for IPv4, and AF_INET+1 for IPv6 addresses.
This prevents the need for a dump and reload, but lets IPv6 parsing
work on machines without AF_INET6.
To select all IPv4 addresses from a table:
select * from foo where family(addr) = 4 ...
Order by and other bits should all work.

specific hash functions used by hash indexes, rather than the old
not-datatype-aware ComputeHashFunc routine. This makes it safe to do
hash joining on several datatypes that previously couldn't use hashing.
The sets of datatypes that are hash indexable and hash joinable are now
exactly the same, whereas before each had some that weren't in the other.

silently resolving them to type TEXT. This is comparable to what we
do when faced with UNKNOWN in CASE, UNION, and other contexts. It gets
rid of this and related annoyances:
select distinct f1, '' from int4_tbl;
ERROR: Unable to identify an ordering operator '<' for type unknown
This was discussed many moons ago, but no one got round to fixing it.

some cases of redundant clauses that were formerly not caught. We have
to special-case this because the clauses involved never get attached to
the same join restrictlist and so the existing logic does not notice
that they are redundant.
|
|
both clauses specify the same targets, rather than always using the
default ordering operator. This allows 'GROUP BY foo ORDER BY foo DESC'
to be done with only one sort step.

here is a patch that allows CIDR netmasks in pg_hba.conf. It allows two
address/mask forms:
. address/maskbits, or
. address netmask (as now)
If the patch is accepted I will submit a documentation patch to cover
it.
This is submitted by agreement with Kurt Roeckx, who has worked on a
patch that covers this and other IPv6 issues.

puts these data structures into static memory, thus saving a few CPU
cycles and two malloc calls per transaction or (in isolation level
READ COMMITTED) per query.

least-recently-used strategy from clog.c into slru.c. It doesn't
change any visible behaviour and passes all regression tests plus a
TruncateCLOG test done manually.
Apart from refactoring I made a little change to SlruRecentlyUsed,
formerly ClogRecentlyUsed: It now skips incrementing lru_counts, if
slotno is already the LRU slot, thus saving a few CPU cycles. To make
this work, lru_counts are initialised to 1 in SimpleLruInit.
SimpleLru will be used by pg_subtrans (part of the nested transactions
project), so the main purpose of this patch is to avoid future code
duplication.

extensions to support our historical behavior. An aggregate belongs
to the closest query level of any of the variables in its argument,
or the current query level if there are no variables (e.g., COUNT(*)).
The implementation involves adding an agglevelsup field to Aggref,
and treating outer aggregates like outer variables at planning time.

but the last client encoding in the enum list is actually PG_GB18030 and
it seems that
#define PG_ENCODING_IS_CLIEN_ONLY(_enc) \
(((_enc) > PG_ENCODING_BE_LAST && (_enc) <= PG_ENCODING_FE_LAST)
can never be true.
I think the define should read
#define PG_ENCODING_FE_LAST PG_GB18030
On the other hand, perhaps no-one cares, because
PG_ENCODING_IS_CLIEN_ONLY is never used.
