Initdb help correction
Changed end/abort to commit/rollback and changed related notices
Commented out way old printing functions in libpq
Fixed a typo in alter table / alter column
|

3 new files and two patches for the plperl subdir.
These changes add the ability for plperl functions
to call 'elog'. It also sets up the frame work to
allow me to add access to the SPI functions.

2-Oct-98 or TODO.detail/cnfify) to decide whether we want to reduce
WHERE clause to CNF form, DNF form, or neither. This is a HUGE win.
The heuristic conditions could probably still use a little tweaking to
make sure we don't pick CNF when DNF would be better, or vice versa,
but the risk of exponential explosion in cnfify() is gone. I was able
to run ten-thousand-AND-subclause queries through the planner in a
reasonable amount of time.

SELECT DISTINCT ON (expr [, expr ...]) targetlist ...
and there is a check to make sure that the user didn't specify an ORDER BY
that's incompatible with the DISTINCT operation.
Reimplement nodeUnique and nodeGroup to use the proper datatype-specific
equality function for each column being compared --- they used to do
bitwise comparisons or convert the data to text strings and strcmp().
(To add insult to injury, they'd look up the conversion functions once
for each tuple...) Parse/plan representation of DISTINCT is now a list
of SortClause nodes.
initdb forced by querytree change...

family functions. Contain:
conversion from a datetype to formatted text:
to_char( datetime, text)
to_char( timestamp, text)
to_char( int4, text)
to_char( int8, text)
to_char( float4, text)
to_char( float8, text)
to_char( numeric, text)
vice versa:
to_date ( text, text)
to_datetime ( text, text)
to_timestamp ( text, text)
to_number ( text, text) (convert to numeric)
PostgreSQL to_char is very compatible with Oracle's to_char(), but not
total exactly (now). Small differentions are in number formating. It will
fix in next to_char() version.
! If will this patch aplly to the main tree, must be delete the current
to_char version in contrib (directory "dateformat" and note in contrib's
README), this patch not erase it (sorry Bruce).
The patch patching files:
doc/src/sgml/func.sgml
^^^^^^^^
Hmm, I'm not sure if my English... :( Check it anyone (volunteer)?
Thomas, it is right? SGML is not my primary lang and compile
the current PG docs tree is very happy job (hard variables setting in
docs/sgml/Makefile --> HSTYLE= /home/users/t/thomas/.... :-)
What add any definition to global configure.in and set Makefiles in docs
tree via ./configure?

(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.

This avoids a lot of redundant cache lookups, particularly in selfuncs.c.
Also, remove SearchSysCacheStruct, which was unused and grotty.

complaints, since this bug existed in 6.5 (and probably long before).
But might as well fix it now that I see it.

fact the same, so I suggest they could be the same file say
geometry-positive-zeros.out, as the main difference seems to be not printing
eg. (0,-0). In src/test/regress/expected, I propose
rm int2-i386-netbsd.out int4-i386-netbsd.out
mv geometry-hppa1.1.out geometry-positive-zeros.out
rm geometry-hppa2.0.out geometry-i386-netbsd.out
and the following patch to resultmap. I have only tested the netbsd results
on i386, but think that in all probability the differences will be the same
for other ports. If it turns out not to be the case, at least we might find
out.

Attached is a small fix for a stupid mistake I made in comment.c
- an attempt to drop a non-existent comment would dump core :-(.
Sometimes, I'm as sharp as a marble.
Sorry,

allows casts without specific length requirements to continue to work
as they did before; that is, x::char will not truncate the value of x,
whereas x::char(1) will. Likewise for NUMERIC precision/scale.
The column length defaults of char(1) and numeric(30,6) are now inserted
in analyze.c's processing of CREATE TABLE.

from a constraint condition does not violate the constraint (cf. discussion
on pghackers 12/9/99). Implemented by adding a parameter to ExecQual,
specifying whether to return TRUE or FALSE when the qual result is
really NULL in three-valued boolean logic. Currently, ExecRelCheck is
the only caller that asks for TRUE, but if we find any other places that
have the wrong response to NULL, it'll be easy to fix them.
