them into the scripts dir. I also added a --list option to show already
installed languages.
This whole moving and renaming totally confused CVS and my checked out
copy got completely fried last night. When you apply the source patch,
please make sure that all the directories src/bin/{create|destroy}* as
well as vacuumdb, cleardbdir are gone and that all the scripts (7) are
in
scripts/.
Meanwhile I am still puzzled about what happened with the docs patch.
Because I don't know what you got now, the second attachment contains
the
files
ref/allfiles.sgml
ref/commands.sgml
ref/createlang.sgml
ref/droplang.sgml

This one should work much better than the one I sent in previously. The
functionality is the same, but the patch was missing one file resulting
in
the compilation failing. The docs also received a minor fix.

and brings into the published interface
PQsetenv.
The first four are asynchronous analogues of PQconnectdb and PQreset -
they allow an application to connect to the DB without blocking on
remote I/O.
The PQsetenv functions perform an environment negotiation with the
server.
Internal to libpq, pqReadReady and pqWriteReady have been made available
across the library (they were previously static functions inside
fe-misc.c). A lot of internal rearrangement has been necessary to
support these changes.
The API documentation has been updated also.
Caveats:
o The Windows code does not default to using non-blocking sockets,
since I have no documentation: Define WIN32_NON_BLOCKING_CONNECTIONS to
do that.
o The SSL code still blocks.

it's better than what used to be there.
* Does proper SQL "host variable" substitution as pointed out by Andreas
Zeugwetter (thanks): select * from :foo; Also some changes in how ':'
and ';' are treated (escape with \ to send to backend). This does
_not_
affect the '::' cast operator, but perhaps others that contain : or ;
(but there are none right now).
* To show description with a <something> listing, append '?' to command
name, e.g., \df?. This seemed to be the convenient and logical
solution.
Or append a '+' to see more useless information, e.g., \df+.
* Fixed fflush()'ing bug pointed out by Jan during the regression test
discussion.
* Added LastOid variable. This ought to take care of TODO item "Add a
function to return the last inserted oid, for use in psql scripts"
(under CLIENTS)
E.g.,
insert into foo values(...);
insert into bar values(..., :LastOid);
\echo $LastOid
* \d command shows constraints, rules, and triggers defined on the table
(in addition to indices)
* Various fixes, optimizations, corrections
* Documentation update as well
Note: This now requires snprintf(), which, if necessary, is taken from
src/backend/port. This is certainly a little weird, but it should
suffice
until a source tree cleanup is done.
Enjoy.

Make all system indexes unique.
Make all cache loads use system indexes.
Rename *rel to *relid in inheritance tables.
Rename cache names to be clearer.
Move around a few other keywords which were not in the right category.
DEC and SESSION_USER are not yet committed to gram.y,

functions. One problem that I have encountered with the function
manager is that it does not allow the user to define type conversion
functions that convert between user types. For instance if mytype1,
mytype2, and mytype3 are three Postgresql user types, and if I wish to
define Postgresql conversion functions like
I run into problems, because the Postgresql dynamic loader would look
for a single link symbol, mytype3, for both pieces of object code. If
I just change the name of one of the Postgresql functions (to make the
symbols distinct), the automatic type conversion that Postgresql uses,
for example, when matching operators to arguments no longer finds the
type conversion function.
The solution that I propose, and have implemented in the attatched
patch extends the CREATE FUNCTION syntax as follows. In the first case
above I use the link symbol mytype2_to_mytype3 for the link object
that implements the first conversion function, and define the
Postgresql operator with the following syntax
The patch includes changes to the parser to include the altered
syntax, changes to the ProcedureStmt node in nodes/parsenodes.h,
changes to commands/define.c to handle the extra information in the AS
clause, and changes to utils/fmgr/dfmgr.c that alter the way that the
dynamic loader figures out what link symbol to use. I store the
string for the link symbol in the prosrc text attribute of the pg_proc
table which is currently unused in rows that reference dynamically
loaded
functions.

and fix_opids processing to a single recursive pass over the plan tree
executed at the very tail end of planning, rather than haphazardly here
and there at different places. Now that tlist Vars do not get modified
until the very end, it's possible to get rid of the klugy var_equal and
match_varid partial-matching routines, and just use plain equal()
throughout the optimizer. This is a step towards allowing merge and
hash joins to be done on expressions instead of only Vars ...
lisp.sgml is a placeholder for Eric Marsden's upcoming contribution.
catalogs.sgml is not yet marked up or integrated.
It should perhaps become an appendix.
No big deal; fixed lots of other markup at the same time.
Bigest change: make sure there is no whitespace
in front of <term> contents.
This will probably help the other output types too.
