recent discussion. The lexer is used for both SQL command text and
backslash commands. The purpose of this change is to make it easier to
track the behavior of the backend's SQL lexer --- essentially identical
flex rules are now used by psql. Also, this cleans up a lot of very
squirrelly code in mainloop.c and command.c. The flex code is somewhat
bulkier than the removed code, but should be lots easier to maintain.

does. (see

wit: Add a header record to each WAL segment file so that it can be reliably
identified. Avoid splitting WAL records across segment files (this is not
strictly necessary, but makes it simpler to incorporate the header records).
Make WAL entries for file creation, deletion, and truncation (as foreseen but
never implemented by Vadim). Also, add support for making XLOG_SEG_SIZE
configurable at compile time, similarly to BLCKSZ. Fix a couple bugs I
introduced in WAL replay during recent smgr API changes. initdb is forced
due to changes in pg_control contents.
Make btree index creation and initial validation of foreign-key constraints
use maintenance_work_mem rather than work_mem as their memory limit.
Add some code to guc.c to allow these variables to be referenced by their
old names in SHOW and SET commands, for backwards compatibility.

* placeholder replacements for sync etc under port.h
To those who are really interested, and there are a few of you: the attached
patch + file will allow the source base to be compiled (and, for some
definition, "run") under MingW, with the following caveats (I wanted to
first properly fix all but the last of these, but y'all won't quit asking
for a patch :-):
* child death: SIGCHLD not yet sent, so as a minimum, you'll need to
put in some sort of delay after StartupDatabase, and handle setting
StartupPID to 0 etc (ie. the stuff the reaper() signal function is supposed
to do)
* dirmod.c: comment out the elog calls
* dfmgr.c: some hackage required to substitute_libpath_macro
* slru/xact.c: comment out the errno checking after the readdir
(fixed by next version of MingW)
Again, this is only if you *really* want to see postgres compile and start,
and is a nice leg-up for working on the other Win32 TODO list items. Just
don't expect too much else from it at this point...

undocumented flexibility that the code historically had and the backend
still has.

Attached are two patches:
- installdoc.patch contains an additional paragraph on the win32 console
codepage for the chapter "Installation on Windows"
Due to a lack of SGML-tools, I have only edited the text and not tested
the SGML code - please check it before merging into the CVS branch.
- psqlcodepage.patch adds the warning about a problematic codepage to psql.

>>ISTM that "source" is worth knowing.
>
> Hm, possibly. Any other opinions?
This version has the seven fields I proposed, including "source". Here's
an example that shows why I think it's valuable:
regression=# \x
Expanded display is on.
regression=# select * from pg_settings where name = 'enable_seqscan';
-[ RECORD 1 ]-----------
name | enable_seqscan
setting | on
context | user
vartype | bool
source | default
min_val |
max_val |
regression=# update pg_settings set setting = 'off' where name =
'enable_seqscan';
-[ RECORD 1 ]---
set_config | off
regression=# select * from pg_settings where name = 'enable_seqscan';
-[ RECORD 1 ]-----------
name | enable_seqscan
setting | off
context | user
vartype | bool
source | session
min_val |
max_val |
regression=# alter user postgres set enable_seqscan to 'off';
ALTER USER
(log out and then back in again)
regression=# \x
Expanded display is on.
regression=# select * from pg_settings where name = 'enable_seqscan';
-[ RECORD 1 ]-----------
name | enable_seqscan
setting | off
context | user
vartype | bool
source | user
min_val |
max_val |
In the first case, enable_seqscan is set to its default value. After
setting it to off, it is obvious that the value has been changed for the
session only. In the third case, you can see that the value has been set
specifically for the user.
Joe Conway
annoyed me the other day while I was documenting my current project. It
makes pg_dump use the same layout for types as for tables, by putting "\n\t"
before the first field and "\n" before the final ");"
Can't really justify this too much except to say I had an itch and I
scratched it ;-)

psql4win32.patch - changes in the psql source code
psql-ref.patch - changes in the documentation psql-ref.sgml
(for new builtin variable WIN32_CONSOLE)
To apply them use "patch -p 1" in the root directory of the
postgres source directory.
These patches fix the following problems of psql on Win32
(all changes only have effect #ifdef WIN32):
a) Problem: Static library libpq.a did not work
Solution: Added WSAStartup() in fe-connect.c
b) Problem: Secret Password was echoed by psql
Solution: Password echoing disabled in sprompt.c
c) Problem: 8bit characters were displayed/interpreted wrong in psql
This is due to the fact that the Win32 "console" uses a
different encoding than the rest of the Windows system
Solution: Introduced a new psql variable WIN32_CONSOLE
When set with "\set WIN32_console", the function OemToChar()
is applied after reading input and CharToOem() before
displaying Output

dropped columns. Fix by using LEFT JOIN rather than straight join
between pg_attribute and pg_type. Also, use pg_type.oid as input to
format_type, so that we don't get a failure on deleted types of deleted
columns (this may be a change we ought to backpatch to 7.3....).
Alias the appropriate columns back to their original name.
Fixed formatting of a few other places as I went along (indenting)

Ok.. that works.
I must say it's a little strange being able to take a constant and say
its no longer constant anymore -- but I suppose it's no different than
defining then undefining pre-processor constants.
