f933766ba7 Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions in
pgsql-hackers.  pg_opclass now has a row for each opclass supported by each
index AM, not a row for each opclass name.  This allows pg_opclass to show
directly whether an AM supports an opclass, and furthermore makes it possible
to store additional information about an opclass that might be AM-dependent.
pg_opclass and pg_amop now store "lossy" and "haskeytype" information that we
previously expected the user to remember to provide in CREATE INDEX commands.
Lossiness is no longer an index-level property, but is associated with the
use of a particular operator in a particular index opclass.

Along the way, IndexSupportInitialize now uses the syscaches to retrieve
pg_amop and pg_amproc entries.  I find this reduces backend launch time by
about ten percent, at the cost of a couple more special cases in catcache.c's
IndexScanOK.

Initial work by Oleg Bartunov and Teodor Sigaev, further hacking by Tom Lane.

d4f4b971a4 Sequences are now based on int8, not int4, arithmetic. SERIAL pseudo-type
has an alias SERIAL4 and a sister SERIAL8.  SERIAL8 is just the same
except the created column is type int8 not int4.
initdb forced.  Note this also breaks any chance of pg_upgrade from 7.1,
unless we hack up pg_upgrade to drop and recreate sequences.  (Which is
not out of the question, but I don't wanna do it.)

5f7c2bdb53 sum() on int2 and int4 columns now uses an int8, not numeric, accumulator
for speed reasons; its result type also changes to int8.  avg() on these
datatypes now accumulates the running sum in int8 for speed; but we still
deliver the final result as numeric, so that fractional accuracy is
preserved.

count() now counts and returns in int8, not int4.  I am a little nervous
about this possibly breaking users' code, but there didn't seem to be
a strong sentiment for avoiding the problem.  If we get complaints during
beta, we can change count back to int4 and add a "count8" aggregate.
For that matter, users can do it for themselves with a simple CREATE
AGGREGATE command; the int4inc function is still present, so no C hacking
is needed.

Also added max() and min() aggregates for OID that do proper unsigned
comparison, instead of piggybacking on int4 aggregates.

initdb forced.

ee8ed85da3 Make LANCOMPILER clause in CREATE LANGUAGE optional. Allow "identifier"
syntax for language names (instead of 'string').

createlang now handles the case where a second language uses the same call
handler as an already installed language (e.g., plperl/plperlu).

droplang now handles the reverse case, i.e., dropping a language where
the call handler is still used by another language.  Moreover, droplang
can now be used to drop any user-defined language, not just the supplied
ones.

ef6ccb0bcc Cleanup some minor oversights in optional-OIDs stuff. 2001-08-10 20:52:25 +00:00

bf56f0759b Make OIDs optional, per discussions in pghackers. WITH OIDS is still the
default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.

Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.

initdb forced.

24641335cf The portion about the PQgetssl() function in the libpq documentation

other). Here is a quick patch to remove one instance of it.

246793469e Modify partial-index-predicate applicability tester to test whether
clauses are equal(), before trying to match them up using btree opclass
inference rules.  This allows it to recognize many simple cases involving
non-btree operations, for example 'x IS NULL'.  Clean up code a little.

fd61fbe837 For some reason, CREATE TYPE has only accepted alignment specifications
of 'int4' and 'double'.  Add 'char' and 'int2' to allow user-defined types
to access the full set of supported alignments.

f59f3c8899 Add a SPI_copytupledesc function that parallels SPI_copytuple --- ie,
it copies the tupdesc into upper-executor memory.  This is necessary
for returning tuple descriptors without leaking all of lower exec memory.

84d2c518fe I noticed that pltcl didn't have any way to get to SPI_lastoid like plpgsql does.. I started using pltcl a lot because I like to decide when and how my queries get planned.. so I put one together really quick
Sorry I don't have the original around to make a quick diff, but its a very small change... I think this should be in the next release, there's no reason not to have it.

its a function with no expected arguments, so you can use it like:
spi_exec "INSERT INTO mytable(columns...) VALUES(values..)"
set oid [spi_lastoid]
spi_exec "SELECT mytable_id from mytable WHERE oid=$oid"

It just didn't make sense for me to use plpgsql and pltcl, or just screw
them both and use SPI from C.
