375369acd1 Replace TupleTableSlot convention for whole-row variables and function
results with tuples as ordinary varlena Datums.  This commit does not
in itself do much for us, except eliminate the horrid memory leak
associated with evaluation of whole-row variables.  However, it lays the
groundwork for allowing composite types as table columns, and perhaps
some other useful features as well.  Per my proposal of a few days ago.

e181001764 Small fix to Christopher's recent improvements --- underscore is not
a special character in regexes, but it is for LIKE, so NOT LIKE 'pg_%'
is incorrect.  Need NOT LIKE 'pg\_%'.

3c9a32d4a2 Fix two bugs in funcs.source that made the tutorial script fail.
Make a LOT of fixes to syscat.source to:

* Set search_path properly (and reset it)
* Add schema name to all results
* Add schema name to ORDER BY first
* Make checks for user-defined objects match reality
* format_type all type names
* Respect attisdropped
* Change !~ to 'not like' since it's more standard

6fbb14a174 Update the complex-datatype example to V1 function calling conventions,
and add binary send/receive functions.  Fix some other grottiness such
as failure to mark the C functions STRICT.

e8db9b26d0 elog mop-up. 2003-07-27 17:10:07 +00:00
fc8d970cbc Replace functional-index facility with expressional indexes. Any column
of an index can now be a computed expression instead of a simple variable.
Restrictions on expressions are the same as for predicates (only immutable
functions, no sub-selects).  This fixes problems recently introduced with
inlining SQL functions, because the inlining transformation is applied to
both expression trees so the planner can still match them up.  Along the
way, improve efficiency of handling index predicates (both predicates and
index expressions are now cached by the relcache) and fix 7.3 oversight
that didn't record dependencies of predicate expressions.

337da0678a Assorted fixes for Cygwin:
Eliminate the mysterious games that the Cygwin build plays with the linker
flag variables.  DLLLIBS is gone, use SHLIB_LINK like everyone else.
Detect cygipc in configure, after the linker flags are set up, otherwise
configure might not work at all.

Make sure everything is covered by make clean.

Fix the build of the new conversion procedure modules.

Add new DLLIMPORT markers where required.

Finally, the compiler complains if we use an explicit
-I/usr/local/include, so don't do that.  Curiously, -L/usr/local/lib is
still necessary.

b663f3443b Add a bunch of pseudo-types to replace the behavior formerly associated
with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

27a54ae282 Opclasses live in namespaces. I also took the opportunity to create
an 'opclass owner' column in pg_opclass.  Nothing is done with it at
present, but since there are plans to invent a CREATE OPERATOR CLASS
command soon, we'll probably want DROP OPERATOR CLASS too, which
suggests that a notion of ownership would be a good idea.

a521d5a25e Update obsolete syntax in example of inheritance. 2002-04-11 21:18:50 +00:00
902a6a0a4b Restructure representation of aggregate functions so that they have pg_proc
entries, per pghackers discussion.  This fixes aggregates to live in
namespaces, and also simplifies/speeds up lookup in parse_func.c.
Also, add a 'proimplicit' flag to pg_proc that controls whether a type
coercion function may be invoked implicitly, or only explicitly.  The
current settings of these flags are more permissive than I would like,
but we will need to debate and refine the behavior; for now, I avoided
breaking regression tests as much as I could.

2e5fda7b7e DROP AGGREGATE and COMMENT ON AGGREGATE now accept the expected syntax
'aggname (aggtype)'.  The old syntax 'aggname aggtype' is still accepted
for backwards compatibility.  Fix pg_dump, which was actually broken for
most cases of user-defined aggregates.  Clean up error messages associated
with these commands.

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.

initdb forced.

d08741eab5 Restructure the key include files per recent pghackers discussion: there
are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively.  By default, only include files meant for frontend use are
installed into the installation include directory.  There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.

623bf843d2 Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group. 2001-01-24 19:43:33 +00:00
5bb2300b59 Revise handling of oldstyle/newstyle functions per recent discussions
in pghackers list.  Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention.  pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'.  A newstyle function must be identified
by an associated info routine.  See src/backend/utils/fmgr/README.
2000-11-20 20:36:57 +00:00
805e431a38 Add support for VPATH builds, that is, building somewhere else than in the
source directory.  This involves mostly makefiles using $(srcdir) when they
might have used ".".  (Regression tests don't work with this, yet.)

Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS).  Add "override" keyword
in most places, to preserve necessary flags even when the user overrode the
flags.
2000-10-20 21:04:27 +00:00
424f0edcb8 Fix relative path references so that make knowns which dependencies refer
to one another. Sort out builddir vs srcdir variable namings. Remove some
now obsoleted make variables.

bec98a31c5 Revise aggregate functions per earlier discussions in pghackers.
There's now only one transition value and transition function.
NULL handling in aggregates is a lot cleaner.  Also, use Numeric
accumulators instead of integer accumulators for sum/avg on integer
datatypes --- this avoids overflow at the cost of being a little slower.
Implement VARIANCE() and STDDEV() aggregates in the standard backend.

Also, enable new LIKE selectivity estimators by default.  Unrelated
change, but as long as I had to force initdb anyway...

091126fa28 Generated header files parse.h and fmgroids.h are now copied into

0dbffa704a First cut at making useful selectivity estimates for range queries
(ie, WHERE x > lowbound AND x < highbound).  It's not very bright yet
but it does something useful.  Also, rename intltsel/intgtsel to
scalarltsel/scalargtsel to reflect usage better.  Extend convert_to_scalar
to do something a little bit useful with string data types.  Still need
to make it do something with date/time datatypes, but I'll wait for
Thomas's datetime unification dust to settle first.  Eventually the
routine ought not have any type-specific knowledge at all; it ought to
be calling a type-dependent routine found via a pg_type column; but
that's a task for another day.

71ed7eb494 Revise handling of index-type-specific indexscan cost estimation, per
pghackers discussion of 5-Jan-2000.  The amopselect and amopnpages
estimators are gone, and in their place is a per-AM amcostestimate
procedure (linked to from pg_am, not pg_amop).

344190b7ef Fixup for src/tutorial/func.c and src/tutorial/func.source
Removed char16 and replaced with an example using Point
as suggested by Tom Lane.  The dept field was changed to
the cubicle field denoting the row(x) and column(y) of
the employee's cube in the corporate jungle.  The C function
builds a 'compromise' cubicle from two suggested ones.

I'll try and patchup the documentation next.
